RFID READERRFID READER

TYPES OF RFID READER Agile Reader

One that can read tags operating at different frequencies.

Dumb reader One that read only one type of tag i.e. of same

frequency. Has very little computing power

Intelligent reader Run on different protocols Can filter data Can run application

Low frequency (125-134KHz)

• Used for shorter read range

High frequency (13.56MHz)

• Used for longer read range

Ultra high frequency (866-915MHz)

• Used for greater read distance but more sensitive

to environment factor

Microwave frequency(2.45-5.8GHz)

Tags will be embedded into the vehicle.

Reader will send electromagnetic waves to the tag.

Power will be drawn by the tag from these waves

Tag will return back vehicle information

Stored in READER memory

Reader will demodulate & convert into digital data
