What is RFID?

RFID is an acronym for radio frequency identification.

Briefly the RF stand for “radio-frequency” and ID means “identifier” that allows an item,

The use of radio frequency tags to identify real objects, for instance a library book, to be identified, accessed, stored, reprogrammed and communicated by using radio waves

Brief History

First Bar code patents – 1930sFirst use of RFID device – 2nd world war – Britain

used RFID-like technology for Identify- Friend or Foe

Commercial Operation begun from 1960’s …In 1970s developers, inventors, companies,

academic institution and government sectors were actively worked on RFID

Most common application were tracked person and objects, identified goods in supply chain, reusable container, high value tools, security, controlling access to building, networks, payment systems and other assets.

Passive TagsPassive Tags Active TagsActive Tags

No battery: passive tags use the incoming signal through induction

Passive tags only function in the closer range (at the most a few meters).

Low cost: Generally, $0.15 to $5.00

Active tags are powered by batteries.

Longer range (100m+)

High cost: Generally, $15 to $100

Types of Tags

Privacy Concerns

Tracking an individual’s movements. If RFID tags are embedded in clothing or vehicles, for example, and if there is a sufficiently dense network of readers in place, it becomes possible to track those tags in time and space.

Sense of limiting or controlling: the revelation of personal information such as medical prescription or personal health histories could have an impact on the availability of insurance or employment;

Information leakage. Consumer rights organizations worry about the possibility that e.g. authorities or thieves will be able to monitor people’s personal belongings through small embedded RFID microchips remaining active after purchase.

Impersonation: Impersonation of RFID tags can be achieved by tag cloning, tag swapping, tag reprogramming or spoofing.

Regulation

Currently no global body governing RFID frequency allocation

In Europe, tags must be removed from packaging before disposal due to recycling disruptions and health regulations

There is limited or no regulation of RFID’s for the most part leading to more controversy

Conclusion

RFID technology is rapidly is becoming more standardized, but problems do still exist

The number of adopters of RFID technology is growing

Regulation and education is necessary to quell some of the fears regarding RFID technology and it’s implications
