RFID systems

The basic RFID system consists of two main components, the small transponder, more commonly known as a tag, which is attached to the item needing identification and the interrogator, or reader, which in some cases is used to both power the tag and read its data without contact. Note that ‘reader’ is somewhat of a misnomer as the device in some cases can actually be used to write to the tag to change its data as well as reading from it. The basic components of the RFID system are shown in :

The range of RFID implementations available are broad, and are covered in more depth in other FIDIS deliverables.
