NFC controller architecture for simultaneous emulation of multiple NFC technologies in one NFC listen device

摘要

An NFC enabled listening device (2) is capable of communication with an NFC enabled reading device in any of several NFC technologies, exemplified by NFC-A, NFC-B, NFC-F and NFC-V. To facilitate selection of the optimum communication technology, and to minimise time and energy consumption, the NFC enabled listening device (2) is provided with a plurality of control modules (4a-4d) each configured to decode only one of the several NFC technologies.
