Data is read from (and written to) the RFID device using various forms of RF communications
Passive devices powered by the interrogator and have no internal battery, active have a battery
Direct line-of-sight is not required to read /write data
Can simultaneously interrogate a number of tags
1. Tag enters RF field 2. RF field interrogates / powers tag 3. Tag transmits ID (plus data) 4. Reader sends data to computer 5. Computer determines action 6. Computer instructs reader 7. Reader transmits new data to tag How Does Passive RFID Work? Antenna Tag Computer
