- 2. RFID = Radio Frequency Identification Electronic labeling
and wireless identificationof objects using radio frequency Tag
carries with its information a serial number Model number Color or
any other imaginable data When these tags pass through a field
generatedby a compatible reader, they transmit thisinformation back
to the reader, therebyidentifying the object
- 3. A basic RFID system consists of thesecomponents: A
programmable RFID tag/inlay for storing itemdata; consisting of an
RFID chip for data storage an antenna to facilitate communication
with the RFID chip A reader/antenna system to interrogate the

They are different from active tags in that they only transmit data
at the time a response is received
