Abstract: A device includes near-field communication (NFC) control circuitry and transceiver circuitry. The transceiver circuitry is coupled to the NFC control circuitry. In a reader mode of operation, the NFC circuitry detects reception of NFC polling frames by the transceiver circuitry. When reception of an NFC polling frame is detected, the NFC control circuitry switches from the reader mode of operation to a card mode of operation.
