Description

Simultaneous NFC reception and transmission system

Typically, in NFC communication between devices or terminals, one device operates in the NFC receiving mode and the other device operates in the NFC transmission mode. Therefore, the two devices cannot transmit and receive NFC at the same time. However, there may be situations in which it is necessary for two devices to transmit and receive data at the same time, respectively. For example, when a passenger's mobile terminal approaches the bus transportation card terminal, the bus-side terminal transmits data A to the passenger terminal, and at the same time, the passenger terminal needs to transmit data B to the bus-side terminal. may exist.
