Anticollision ; Anticollision

Procedure enabling a reader to take an inventory of the tags present in its field of action. Depending on the protocol used, a reader can identify several hundred tags in just a few seconds.

Communication en champ proche (NFC); Near Field Communication

A type of RFID system in which the tags' operating zone lies within the near-field zone created by the reader. The coupling between tag and reader is generally inductive. LF (125 kHz) and HF (13.56 MHz) RFID systems are systematically near-field.

Coupling; Coupling

Coupling defines the connection between a tag and a reader. LF and HF RFID systems generally feature inductive coupling. In this case, the magnetic field is used to transmit energy and data. UHF and SHF RFID systems use electromagnetic...
