    1. IntroductionZigBee Retail Services helps retailers reinvent the

    shopping experience for a customer-centric process by

    ayering new control capabilities into everyday tasks.

    With this innovative technology, ZigBee Retail Services

    enables retailers to increase productivity, strengthen

    customer loyalty and streamline operations with theunderpinnings of a comprehensive data-driven

    nfrastructure tailored to the retail environment. The

    underlying mesh network infrastructure provided by

    ZigBee is ideal for implementing the retail service

    components of a system that enhances the shoppers

    experience and brings greater efficiencies to retailers.

    Standardized retail services solutions enable retailers

    to build networks incrementally and cost-effectively

    with components, and to scale by adding additional

    devices with specific functions without expanding the

    network infrastructure or integrating new software

    nto the retail systems back-end servers.

    Figure 1: Holistic approach to the retail ecosystem

    The ZigBee Alliance-defined components automate

    the retail environment to enhance shoppers

    experience, such as: More consumer control Help in remembering what to buy

    Locating products easily

    Determining the price of an item

    Finding help easily when needed

    Reduced wait time to pay and bag items

    The components bring efficiencies to the retailer

    through: Data collection

    Shelf item management

    Inventory management

    Asset management

    Physical plant management

    Personnel management Risk abatement

    Reduced shrinkage and spoilage

    In order to facilitate shoppers active participation an

    retailer efficiencies, we envision enabling many of th

    key components of the retail space with ZigBee

    systems, creating a holistic wireless network that

    includes the shoppers themselves, Intelligent

    Shopping Carts, and shelf tags.

    2. Defining a New Customer ShoppingExperience

    Imagine a customer arriving at a store with a portab

    electronic Personal Shopping Assistant. As the

    customer approaches the store, the handheld device

    communicates with and then joins the stores holisti

    retail network. When the shopper chooses an

    Intelligent Shopping Cart that is already part of the

    stores network, the Personal Shopping Assistant

    creates a relationship with the cart that the networkunderstands and, more specifically, the back-office

    retail server understands.

    At the same time, the networks location engine star

    a trace of the Personal Shopping Assistant and the

    Intelligent Shopping Cart that records the shoppers

    movements through the store and the parking lot.

    If the shopper uploads a shopping list prior to arrivin

    the retail server communicates the best way to

    navigate the store using the shopping list.

    Furthermore, the retail server also informs the shopp

    about special offers or other promotional events suc

    as coupons related to the shopping list. If the Person

    Shopping Assistant indicates the need for a

    prescription, the network triggers an order for the in

    store pharmacy and adds the directions to the picku

    window to the customers shopping path. Should th

    customer need help, store personnel can get to the

    customer quickly assisted by the location engine.

    Finally, the customer is able to breeze through

    checkout as the items in the cart have already

    been scanned.

    FIgure 2: Customer or Cart Interactions

    The ZigBee Retail Services standard defines the

    messages being exchanged between the Personal

    Shopping Assistants, the carts and the retail server. The

    ZigBee PRO specification, the base networking system,

    handles the joining and authentication process, whichs guided by notes in the ZigBee Retail Services

    standard. With messaging, the retail tunnel cluster

    covers the specific application messages between the

    Personal Shopping Assistant and the retail server, and

    the ZigBee Telecom Services location cluster covers

    ocation services. All are standard ZigBee messages.

    As the customer shops, scanned items and Personal

    Shopping Assistant information are communicated to

    he retail server through retail tunnel messages. As theback office receives UPC messages from the customers

    Personal Shopping Assistant, it compares the weight

    change reported by the load cell in the Intelligent

    Shopping Cart with the known weight of the item

    hrough its UPC code. If the weights match, the item is

    accepted and a text message or another feedback

    mechanism displays on the Personal Shopping

    Assistant. However, if there is a discrepancy, the

    customer receives an alert on the mismatch and

    instructions on how to correct the discrepancy. The

    system tracks if a particular customer is having troub

    by registering a high number of discrepancies and it

    dispatches a retail associate to help based on locatio

    information from the shoppers handheld device.

    As the customer continues to shop, the retail server

    builds the invoice for the cart, as well as other logisti

    data about the customers path through the store.

    The system recognizes that the customer is ready to

    leave when the customer enters a checkout area. Th

    retail server transmits the invoice through the retail

    enterprise network to a POS system that enables the

    customer to complete the transaction.

    The customer can then leave the store with the item

    When the Personal Shopping Assistant leaves the

    holistic retail network, the relationship between the

    cart and the Personal Shopping Assistant is severed.

    In the scenario described above, much of the

    complexity of the mobility of the Personal Shopping

    Assistant and the cart is hidden from the customer. F

    example, in cellular networks, mobile devices that ar

    end nodes move about and need to migrate from

    router to router or access point to access pointdepending on the specific network implementation

    This mobility causes the mobile devices to roam

    various access points as they move, and this, in turn,

    causes the holistic retail networks routing tables to b

    in continual flux. ZigBee in general, and the ZigBee

    Retail Services and ZigBee Telecom Services in

    particular, are designed to handle complexity of this

    mobility, making it possible to have mobility and

    efficient network use in the same dynamic

    environment.

    This use provides customers with an in-store

    experience that enables them to shop at their own

    pace, check prices easily, view their running financia

    total as they shop, locate products, scan and bag

    products their way, and minimizes the touching of

    items by others, pay for goods with minimal store

    associate interaction and experience minimal audit

    processes. In addition, it allows for payment with

    minimal associate interaction, and minimizes audit

    processes. This experience carries over to at-home

    shopping uses that enable the creation of shopping

    ists, price comparisons, and coupon offers. It also

    reduces out-of-stock situations when customers

    arrive at the retailer. Additional services could

    nclude support for pharmacy services or allergy

    alerts. What this really boils down to is an experience

    where the customers have complete control of their

    shopping experience, at their own pace with

    opportunities, gently aided by the technology, to

    save time and/or money.

    3. ZigBee Retail Services DevicesThe core ZigBee Retail Services devices envisioned in

    the system includes:

    Personal Shopping Assistant: Customer devices

    with a bar code scanner to read Universal Product

    Code (UPC) labels on products, a two-way

    communication display, a keypad, audio

    components, and more.

    Intelligent Shopping Cart: Standard shopping

    carts equipped with a load cell designed to sense

    weight similar to self-checkout kiosks used at

    grocery stores today.

    Fixed Access Points: The process of one device

    connecting to another device in the holistic retail

    network including the retailers back office and a

    gateway device sitting between the stores holistic

    retail network and back office.

    Figure 3 provides a system-level diagram of the typical

    nfrastructure.

    Figure 3: System-level diagram of a Retail Services implementation.

    Other ZigBee Retail Services devices include: Employee Customer Concierge: A device similar to

    the Personal Shopping Assistant with added

    management capabilities to help locate and assist

    customers, re-stock shelves and complete

    personal shopping tasks.

    Electronic Shelf Labels: Digital displays with price

    and product information. Asset Tracking Tags: Devices applied to pallets,

    forklifts, hand carts, ladders, maintenance and

    cleaning equipment, and other high-value assets

    which enable decision-making based on historica

    location data.

    Electronic Shelf Edges: Larger multi-media display

    devices showing advertising, product information

    movies and more.

    Other Components from ZigBee Standards:

    Components such as ZigBee Building

    Automation for environmental control, ZigBeeHealth Care for pharmacy/clinic operations,

    ZigBee Light Link for lighting control, ZigBee

    Remote Control for display device controls, or

    ZigBee Smart Energy for energy management.

    The ZigBee Retail Services network also extends in

    the shoppers home, enabling the shoppers

    handheld Personal Shopping Assistant or ZigBee-

    equipped smartphone to interact with the retailer

    enterprise network through an in-home gatewaydevice. This would enable the customer to take

    control of their shopping experience even before

    they have left their home.

    4. Key Use CasesA number of routine activities benefit from increased

    connectivity and control. Below are several key areas

    addressed by ZigBee Retail Services.

    1) Advanced Shopping: The use of ZigBee handheld

    devices and shopping carts lets stores personalize

    and customize each shoppers experience.

    Shoppers scan items just once using a Personal

    Shopping Assistant before placing them in the

    Intelligent Shopping Cart. Personal Shopping

    Assistants connect to the holistic retail network

    seamlessly and communicates the UPC

    information of each item and the incremental

    weight change in the cart to a back-end server. It

    ZigBee Retail Services Delivering Next Generation Shopping Experience October

    6

  • 8/13/2019 ZigBee WhitePaper NextGenerationShopping Wkg2c (3)(RS)(Oct-7)

    7/13 2013 ZigBee Alliance. All rights reserved. www.zigbe

    is then verified and added to the ongoing list of

    items the shopper has collected and may trigger

    customized purchase recommendations, sales or

    special offers. If the incremental weight reported

    by the shopping cart correlates with the recorded

    weight of the item scanned, the Personal

    Shopping Assistant adds it to the shopping list. If,

    on the other hand, the weight does not correlatewith the item, the customer receives a message

    on the Personal Shopping Assistant directing the

    customer to either rescan the item or return it to

    the shelf. It would also trigger an alert to the

    support staff of the retail facility to assist the

    customer if necessary, for instance if the customer

    is scanning an item multiple times but the PSA is

    not adding it to the shopping list which would

    indicate some technical glitch.

    The Personal Shopping Assistant can exchange abroad range of information with the retailers

    back-end servers and personalize a customers

    shopping experience.

    For example:

    Current shopping and loyalty (if applicable)

    information

    Daily sales information

    Forthcoming sales opportunities

    Real-time customer information (e.g, notice

    to/from pharmacy such as prescription isordered/ready)

    Special retail offers for preferred customers

    Help requests to/from Retail Associates, product

    location services

    n conjunction with the location engine that is part of

    he holistic retail network, the Personal Shopping

    Assistant updates information on items that the

    shopper is approaching based on the shoppers

    projected path through the store.

    The announcements on the Personal Shopping

    Assistant could also be tailored using shopper-specific

    profiles that determine the level and variety of

    announcements that the shopper wants to receive.

    These announcements might be: Product advertisement

    Alerts (such as health and ingredient conflicts)

    Personalized downloading based on customer

    profiles and shopping lists

    The Personal Shopping Assistant also provides two-

    way voice and text or short messaging service (SMS)

    like communication with store personnel.

    2) Customer-Centric Personal Shopping Assistant

    Used at Multiple Retailers: In some situations, the

    customer owns the Personal Shopping Assistant

    instead of the retailer. As such, the shopper would

    carry the device home as well as to other retail

    locations and potentially competitive retailers.

    Some scenarios include the use of the Personal

    Shopping Assistant in retail mall environments or

    at different retailers within the same complex. The

    Personal Shopping Assistant becomes an essentia

    part of the customer shopping experience as the

    shopper moves from store to store.

    A variation of this general case is the use of the

    Personal Shopping Assistant at multiple locations

    of the same retailer, potentially even

    internationally. Here, the retailers enterprise

    systems allows shoppers information and system

    access credentials to be distributed to a specific

    store location when shoppers visit with their

    Personal Shopping Assistant.

    3) Customer Retail At-Home Experience: With a

    customer-centric handheld ZigBee device at

    home, the customer can build shopping lists or

    inquire about product availability using the

    Personal Shopping Assistant through a

    gateway device that communicates with the

    retailers enterprise services over the Internet.

    Further, when a customer arrives at a store with

    a preloaded shopping list, the Personal

    Shopping Assistant guides the customer

    through the store using the most efficient path

    This eliminates the need to walk up and down

    aisles looking for specific items or looking for

    help finding specific items.

    4) Asset Tracking and Customer Behavior: The

    shoppers Personal Shopping Assistant and

    Intelligent Shopping Cart are tracked thereby

    gathering critical shopping behavior data and

    tracking of store assets. Retailers gain insight

    ZigBee Retail Services Delivering Next Generation Shopping Experience October

    7

    8/13 2013 ZigBee Alliance. All rights reserved. www.zigbe

    into how and where customers move through

    the retail floor space, how long they pause at a

    specific location, locations where they do not

    shop and how quickly or slowly they travel

    through specific areas. This data provides

    feedback into how well areas of the retail floor

    plan are performing and how and where to

    improve merchandising and increasemarketing opportunities. In an emergency,

    specific tracking data helps to locate customers

    in distress. Alternately, using this same location

    feature for the Intelligent Shopping Cart, it

    provides asset tracking of the cart itself or

    other items in the store that are mobile and in

    jeopardy of being removed.

    5) Personnel/Inventory Tracking: As with the

    Personal Shopping Assistant, retail associates use

    an enhanced version of the device to track itemson the shelf for stocking or re-stocking. With the

    device location feature, management monitors

    associates effectiveness at specific tasks using

    real-time interaction with the retail back-end

    server to provide detailed task management and

    reporting.

    6) Electronic Shelf Labels and Shelf Edges: Shelf

    labels, the electronic versions of price tags,

    product information, and sales information seen

    on the retail shelf today, allows for two-wayradio contact with the retailers back office. The

    primary goal is to enable the retailer to update

    pricing and other critical information displayed

    on the shelf tags in real time and at the push of

    a button. More advanced scenarios have the

    shelf tags interacting with the back-end server

    location engines to personalize shelf tags when

    customers approach the item in question. A use

    case for this is to flash the display on the tag

    when an approaching shopper has that item on

    the handheld shopping list, thereby drawing

    attention to the items location.

    7) ZigBee is ideal to accomplish the sensing and

    communications processes required for tasks

    associated with supply chain management.

    Managing this side of the retail equation improves

    the way a company finds the raw materials it

    needs to make a product or service and deliver it

    to customers. In the context of the retail

    environment, it involves:

    Obtaining raw materials for production of

    marketable goods

    Asset tracking (e.g., people, forklifts, hand

    trucks, pallets, tractor trailers, special materials)

    Just-in-time inventory

    Virtual demand and predictive inventory Cold chain management

    Delivery loading/unloading

    Warehousing/location of raw materials and

    products

    Monitoring temperatures, humidity, unusual

    motion, salinity, spills, etc.

    Monitoring sort systems in warehouses

    Monitoring activities for safety and security

    (e.g, video)

    Maintain telematics information for trucks and

    other vehicles Return/exchange strategy

    These factors are the critical elements of

    successful supply chain management. As an

    example, ZigBee technology is already being used

    for monitoring the integrity of refrigeration in

    truck fleets transporting perishables. Wireless

    sensors deployed in pallets to monitor that the

    correct temperature is maintained from origin to

    destination can be mesh networked using ZigBee

    and the information can be sent regularly to thecentral servers. Since ZigBee technology is ultra-

    low power it is well suited even for long distance

    transportation. When the trucks reach their

    destination the monitoring data for the trip can be

    sent to the systems in the receiving facility and

    any pallet that was not maintained at the right

    temperature through the trip can be easily

    identified and not offloaded at all. This proactive

    ability to identify refrigeration failures can help

    minimize spoilage, avoidable paperwork like

    insurance claims etc. The same network can also

    be leveraged to identify spillage en route. This can

    have a huge impact on businesses in reducing

    operating costs and quality issues.

    8) Other ZigBee standards, including ZigBee Building

    Automation, ZigBee Health Care, ZigBee Smart

    Energy and ZigBee Light Link, specifically relate

    to retail operations, safety and security. These inclue

    Food Safety Management to report storage

    temperatures, humidity conditions in coolers,

    meat lockers and more.

    Temperature alerts for other appropriate areas

    as required (such as meats or dairy)

    HVAC systems monitoring

    Open/close restricted entrances, windows, etc.

    monitoring Health hazards/high-risk areas monitoring

    Safety alerts (for fire, flooding, earthquakes, etc.)

    Shelf-stocking issue monitoring

    The efficient operation of lighting systems, control

    of temperatures and preventive maintenance can

    represent significant savings for any retailer. For

    larger retail chains that can include thousands of

    stores and other facilities, it can result in

    substantial savings. Large retailing leaders such as

    Kroger are very committed to supporting food atsafe temperatures, which entails very accurate and

    reliable monitoring of coolers, produce, meat and

    other perishables. This has an impact on safety for

    consumers and also the lifespan of products. For

    example, strawberries should last four to five days

    after purchase but if they have been exposed to

    higher temperatures, they will not last that long.

    Not only does ZigBee technology enable retailers

    to keep out of specification products from being

    sold to customers, but also assists in preventive

    maintenance of devices reducing spoilage andenergy wastage. Energy savings can translate into

    big dollars and in fact, studies have shown that

    the energy saved is equivalent to one years

    payback of infrastructure cost.

    Linking the monitoring and control of the physical

    plant to other aspects found in the ZigBee Retail

    Services standard such as personnel tracking, can

    yield further benefits in terms of safety, reporting,

    and risk mitigation.

    A prototypical system diagram displays below.

    FIgure 4: General System Diagram

    5. Location engineA key component of ZigBee Retail Services is the

    location engine, a system which tracks the location o

    all radio-enabled elements, or more typically, trackinthe location of the mobile elements, the Personal

    Shopping Assistant and the Intelligent Shopping Ca

    The devices which require location tracking can use

    the Location Cluster from the ZigBee Cluster Library.

    This cluster provides a means for exchanging Receiv

    Signal Strength Indication (RSSI) information among

    one-hop devices as well as messages to report RSSI

    data to a centralized device that collects all the RSSI

    data in the network.

    The example below displays the usage of the RSSI

    ocation cluster:

    Figure 5: Location Engine

    This mechanism forms the basis for all the tracking

    mechanisms in the ZigBee Retail Services standard

    from customer tracking through asset tracking and has

    a significant impact on the quality of service being

    delivered by the retailers.

    6. The Better SolutionAdvanced retail services are ideally suited for ZigBee

    wireless technology versus 802.11 (wireless

    technology) because retail mobile devices require low

    cost, long battery life, high security (encrypted data)

    and maximum location accuracy.

    Most ZigBee devices are typically in sleep mode

    until they need to communicate data. Compare

    this to always-powered-on 802.11 devices that

    must be mains powered or require repeated

    charging during the course of the day.

    ZigBee uses radio technologies with blocking

    features specifically designed to reduce

    unwanted radio signals. This allows ZigBee

    devices to get their messages through on the

    first try. Repeated retransmissions reduce total

    battery life and add latency into devices

    receiving information. By contrast, 802.11

    devices are naturally very chatty. These frequent

    and unnecessary message status transmissions

    reduce battery life.

    ZigBee devices operate on a secure network

    allowing devices to enter and exit the network.

    Each one of these ZigBee devices only operates

    with another secure device in the network.

    ZigBee networks use robust mesh technology

    with built in redundancies and no single point ofailure, versus a star network used by 802.11.

    ZigBee routing devices pass data, allowing a

    small number of devices to achieve greater total

    range than any 802.11 network. 802.11 devices

    use a star network, requiring the receiving

    device be within range of the transmitting

    device with potential for points of failure.

    7. Payment ScenarioWhen the customer reaches a Point-of-Sales (POS)

    station, an invoice for the items scanned and added

    the Intelligent Shopping Cart is presented

    automatically to the shopper with payment options.

    The retail systems back end communicates the

    information for the invoice to the POS system. The

    location engine in both the customers Personal

    Shopping Assistant and the Intelligent Shopping Ca

    triggers the checkout process as the shopper enters

    the checkout area. With the handoff completed, the

    POS system, which is not specifically part of the reta

    services profile but still an essential part of the overasystem, takes over, enabling the shopper to speedily

    pay for the items and exit the store.

    8. Retail Employee Use CaseThe retail-employee use case is similar to the

    customer handheld case. The two devices are very

    similar, and often, the same device. The usage

    scenarios differ from the customers use. In particular,

    the retail employee uses the device, at a minimum,

    to track the location of the Retail Associate over timeto allow for labor tracking. The UPC scanner in the

    device is used for shelf-level inventory control, a

    scenario that is the opposite of the customer

    shopping experience; the item is registered as added

    to the shelf rather than removed. The item scans

    provide the back-end servers with the information

    needed to manage shelf-level inventory. The

    Employee Customer Concierge device is used for

    UPC scanning and still images, shelf-level inventory

    control, capturing photos for security, compliance,

    and task completion audits. Through the devices

    display and potential two-way audio components,

    management can communicate directly with the

    retail associate to provide updates or revised work.

    9. Electronic Shelf Labels and ElectronicShelf Edges

    Future releases of ZigBee Retail Services are expected

    to address the use of electronic shelf labels and multi-

    media shelf edge devices that would replace the

    current shelf tags that display pricing for the items onthe shelf and other item-oriented information. The

    electronic shelf tag is a display device that allows the

    tem information, such as a description and its price, to

    display to the customer and allows updating of this

    nformation on tag-by-tag basis through the holistic

    retail network.

    Other functions the tags might perform are alerting

    specific customers to special offers or alerting the

    shopper to the shelf location of an item when theshopper is in the area. This can help the retailer in

    accomplishing higher sales per visit by the customer.

    Figure 7: Electronic Shelf Label Interactions

    10. In-home scenarioThe customer Personal Shopping Assistant is a speci

    retail device that is used in multiple networks. The

    customer may register with multiple retailers, as welaccess the retail information from locations other tha

    the holistic retail network (e.g., from their home,

    friends homes, hotspots, hotels, etc.) The most

    prominent example is of a consumer connecting the

    Personal Shopping Assistant via a gateway at home.

    With the device at home, the customer creates

    shopping lists and checks item availability or price

    prior to visiting the store, either by entering the data

    on the device or by scanning an items UPC.

    11. SecurityThe data generated by ZigBee Retail Services devices

    contains confidential information with respect to

    health care and mobile payment, money-sensitive

    nformation regarding pricing and offers, and other

    mportant information regarding the control of

    equipment used to store goods and track assets. While

    security requirements differ slightly with different

    types of data, all of it should be protected from

    unauthorized usage with respect to confidentiality,

    ntegrity, and authenticity.

    Confidentiality: For Consumer Privacy, some of the

    information transferred in the network is relevant

    for consumer privacy. Thus, confidentiality of the

    whole data flow needs to be protected for a

    medium timeframe.

    Fraud Protection: Some information directly linked

    to transactions that have monetary value should

    be protected in terms of integrity and

    authenticity, and should be capable of standing

    up in court. Associates who may try to manipulate

    the system in order to manipulate their work

    schedule, may also commit fraud.

    Protection of Control Networks: The network

    sends control information to both devices and

    associates. This information should be

    authenticated.

    Court Provability (where allowed): Some of the data

    collected by the system can be used to demonstrate

    that certain events did or did not happen, for examp

    that an associate was present at a particular spot at a

    particular time. In the extreme case, this data may be

    used for legal purposes, and thus, needs to provide

    sufficient tamper protection due to the varying

    requirements of the different retail applications, ZigB

    Retail Services allows devices to either rely on netwo

    level security alone, or add application level security

    applications with higher security requirements.

    Devices under the control of the device owner (e.g.,

    devices taken home by the customers) are especially

    vulnerable to attacks.

    Ultimately all ZigBee Retail Services devices support

    network-level security (i.e. the network keys shall no

    be well known). This network key communicates wit

    the devices through a set of encrypted messages to

    site-specific Trust Center link key. The Trust Center Lin

    keys are under the direct control of retailers.

    Using network-level security provides protection

    against sniffer devices that are not part of the netwo

    while also providing protection from rogue devices

    trying to disrupt the network.

    The network can provide additional security at the

    application layer using application layer link keys

    which provide peer-to-peer encryption andauthentication and/or retailer-specific encryption th

    can be applied to the retail tunnel payload.

    12. SummaryZigBee Retail Services benefits both the retailer and

    the customer with enhanced services through

    automation of many retailer operations and custome

    touch points. Retailers benefit from using new

    technology that helps increase productivity, encoura

    customer engagement, increase quality of service anrevenues, reduce spillage and spoilage, save on ener

    costs and reduce the number of devices needed to

    shopping experience, create their shopping lists at

    home, load coupons, and use their list for guidance

    within the store. Customers also benefit from an

    enhanced customer experience by automating the

    scanning and checkout processes.
