RFID, Radio Frequency Identification, involves three components.  First it has a tag consisting of a microchip and radio antenna.  Second is a reader.  And third is a computer system.  The tag is attached to or embedded in an item such as an employees’ building entrance pass.  Information contained in the chip is sent to the reader by radio signals.  The device translates those signals and delivers the information to the computer system.  The computer system can use the information in a variety of ways, depending on what it’s set up to do.  Depending on their intended use, RFID systems vary in the amount and sensitivity of information that the chips contain and the distance from which readers can pick up the signals from the tags.  Keep your eye on this blog for more fascinating information on RFID.
