2.2 An Overview Of Rfid Systems

An RFID system consists of two components: a transponder, or a tag and a reader, or an interrogator. The transponder carries the actual data and is attached to the object to be identified. RFID systems are categorized according to fundamental operating principles, tag complexity, operating frequency, range and powering methods.

As a major classification, according to the power source, tags are classified into three categories:

  • •

    Passive tags: Tags with no built-in power source.

  • •

    Semi-passive tags: Tags that use batteries for some of their operations.

  • •

    Active tags: Tags that use batteries as their sole source of energy.
