RFID Basics

What is automatic identification?Automatic identification is used to identify items, captureinformation and get the data into a computer.

Aims:

increase efficiencyreduce data entry errors

free up staff to do other value added functions

Examples:barcode

RFID (radio frequency identification)

RFID Basics

Advantages of RFID vs. Barcode

No requirement for line-of-sight

Dynamic information carrier (read/write)

High memory capacity if needed

Anti-collision (many tags can be read at the same time) Robust and reliable

Performs in rugged, harsh environment

Cheaper in long term

No human intervention Reader virtually maintenance free

RFID Basics

How RFID Systems work

RFID tag gets into reading device's

electromagnetic field

tag receives the signal which

energizes the passive tag

tag transmits the data stored in the

IC in return

reader passes the information to the

host system

host system can be connected into

the Internet or company's ERPsystem

reader can also pass information to

the tag which can be re-written or

deactivated

RFID Basics

Primary RFID Application Areas

Supply chain management

Mass transit

Postal and courier services

Food industry

Library systems

Healthcare, pharmaceutical industry

Access management

Anti-counterfeiting

Toll collection

Airline baggage handling

Animal identification

Document tracking

RFID Basics

Passive RFID tagsNo internal power source

IC (integrated circuit) - provides the

memory and stores data

Antenna harvests power &

communicates with the reader

Inlay/inlet IC and antenna

assembled together for insertion

RFID tag an inlet converted in a

way that it can be applied to an

object

RFID Basics

RFID Frequencies

125-134 KHz LF: Low Frequency

13.56 MHz HF: High Frequency

862-928 MHz UHF: Ultra High Frequency

2.45 GHz Microwave 5.8 GHz Microwave

Different applications, different RFID

frequencies

UPM Rafsec believes that HF and UHF will co-exist in the RFID

tag market. One cannot do without the other.

UHF Frequencies

Europe: 868 MHz

USA: 915 MHz

Korea: 908.5914 MHz

Singapore: 866-869 & 923-925 MHz Japan: 950 MHz (pending)

EPC Global

A joint venture between EAN International in Europe and theUniform Code Council (UCC) in USA

Carries forth the work completed by the Auto-ID Center

EPCglobal is leading the development of industry-driven

standards for the Electronic Product Code (EPC) to supportthe use of Radio Frequency Identification (RFID)
