Hello Lawrence,

the TRF7962 has limitations in the ISO14443A protocol, which requires software workarounds. These are fixed in the TRF7962A Version.

A document which describes the limitations can be found here:

You wrote in your question also about P2P. If you mean Peer-to-Peer, this is not possible with the TRF7962. Only the TRF7970 will support P2P.

Best regards,

Helfried
