A basic RFID system consists of three major parts:

  • RFID tags that are attached to the objects to be identified.

  • Fixed or hand-held RFID readers that read tags and send data to the IT system.

  • An IT system capable of collecting, storing and elaborating on the data sent by the readers.

Tags along with their features are likely the part that mainly characterizes an RFID system.
