A near field communication reader adapted for NFC A anti collision and a method of NFC A anti collision

摘要

In near field communication (NFC) a reader (PCD) (1), may be embodied in a smart mobile phone (1). The reader has a controller (2) controlling a transmitter 6 and a receiver (7) to transmit and receive signal in accordance with the NFC Forum and other specifications. The reader operates a method to resolve signal collisions between multiple NFC type A technology tags (i-vi), also known as PICCs or listen devices proximate when the reader generates an activating radio frequency field.
