R.F.I.D.(Radio Frequency Identification)
R.F.I.D.
• RFID Definition– Radio-frequency identification (RFID) is an
automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.
RFID History
• In 1946 Léon Theremin invented an espionage tool for the Soviet Union
• RFID tags are passive, active, and semi-passive• Requires no internal power supply, the
antenna from the rfid tag picks up power from the transmitter
Facts of R.F.I.D.
• Data capacity for each R.F.I.D. is big enough so each R.F.I.D. code will have its own unique identify – unlike barcodes which are the codes are the same
for each product.
• an R.F.I.D. tag can store 2kb of data
Uses of R.F.I.D.
• Weather Forecasts• Senses of Road Conditions with Use of
Beacons• Noise level Monitoring• Retail Theft Protection• Personal Identification• Information Tracking Systems• I-Pass
Why Is This Technology Still Emerging?
• RFID tags cost 20 cents a piece• High standards for UHF signal which is used to
read RFID tags• RFID tag readers cost about 1000 a piece,
companies would need many of these for their warehouses, etc.
