RFID stands for "Radio Frequency IDentification". This technology enables an object to be identified, to follow its path and to see its characteristics remotely thanks to a label that emits radio waves and is attached to or incorporated into the object. RFID technology enables several labels to be read, even without a direct line of sight, and may pass through all materials other than water and metal.
The radiofrequency label (transponder, RFID label), is composed of a chip connected to an antenna, encapsulated in a support (RFID Tag or RFID Label). It is read by a reader which captures and transmits the information.
There are two main families of RFID labels:
UHF RFID tags are in EPC format (Electronic Product Code), representing "the object traceability network". In particular, this provides for unitary object identification (sequential coding labels) and is attached to an Internet data sharing network. EPC has been driven by major world commerce and information system industry actors. It was developed by MIT (Massachusetts Institute of Technology). It is developed and promoted in France by EPC Global France, a spin-off from GS1-France (ex Gencod-Ean France).
