APPLICATIONS OF RFID (RADIO FREQUENCY IDENTIFICATION)



VOCABULARY

To track: To follow (a track, course, etc.).

Attributes: A quality or feature regarded as a characteristic or inherent part of someone or something.

Pets: A domestic or tamed animal or bird kept for companionship or pleasure.

Espionage: Involves a government or individual obtaining information considered secret or confidential without the permission of the holder of the information.



MEANING

Radio Frequency Identification (RFID) technologies provides a means to wirelessly identify, monitor and track individuals or products. With recent improvements in capability and performance, RFID systems are being applied in an every increasing range of industrial and consumer applications.

Holds a small amount of unique data – a serial number or other unique attributes of the item

The data can be read from a distance – no contact or even line of sight necessary

Enables items to be individually tracked from manufacture to consumption

Many uses: Logistics, Military, Pets.

RFID HISTORY

Technology used in RFID’s was first developed in the 1920’s

First used by Soviet’s in 1945 as an espionage tool (passive, covert listening)

Similar technology, the IFF transponder, was used by the British in WWII to identify airplanes as “friend or foe”

A 1948 paper by Harry Stockman first explored the vast potential for RFID technology

RFID “systems” did not appear until the 1960’s

RFID’s are currently used for:

– Inventory Monitoring• Library book and bookstore tracking• Pallet tracking (Wal-Mart and the Dept. of Defense)

– Access Control• Hand Implants• ID badges (Mt. Bachelor ski resort season passes)

– Payment Systems• The American Express Blue Card, a feature they call Express Pay• Exxon Mobile SpeedPassAirline baggage tracking• Cell phones are including RFID tags built in• High-end VIP nightclubs

– Commercially for truck and trailer tracking in shipping yards

– Long range access control for vehicles • Entry gates• Electronic toll collection

RFID - CURRENT USES



RFID Implants

Before After implant surgery



RFID Concepts

A non-contact system that can monitor and track items or individuals.

Provide unique identification that allows for a wide range of applications.

Perform the operation using unobtrusive, “low cost” components.

Use Wireless Communication techniques to facilitate the system design.



FOUR PRIMARY FREQUENCY BANDS HAVE BEEN ALLOCATED FOR RFID USE

Low Frequency (119/136KHz) – most commonly used for access control and asset tracking.

Mid-Frequency (13.56 MHz) – Used where medium data rate and read ranges are required.

Ultra High-Frequency (850 MHz to 950 MHz and 2.4 GHz to 2.5 GHz) – offer the longest read ranges and high reading speeds.
