By using an SDR receiver it is possible to capture, demodulate and decode the NFC signal between the card and the reader. Currently, detection and decoding is implemented for:

• NFC-A (ISO14443A): 106kbps, 212kbps and 424kbps with ASK / BPSK modulation.
• NFC-B (ISO14443B): 106kbps, 212kbps and 424kbps with ASK / BPSK modulation.
• NFC-V (ISO15693): 26kbps and 53kbps, 1 of 4 code and 1 of 256 code PPM / BPSK modulation (pending FSK).
• NFC-F (ISO18092): Preliminary support to 212kbps and 424kbps with manchester modulation.
