Hello @marvelouzz667,

Hope you are doing well.

You can refer to Using the RC663 without library. This document describes how a host processor interacts with the RC663 via an SPI interface and shows an example flow for ISO 14443 and line by line description.

Regards,
Eduardo.

i've seen this document, however it doesn't seem to have for iso14443b only iso14443a and iso15693

Hi,

The same approach should apply. Please refer to CLRC663 Data Sheet for more information on the parameters related to ISO14443-B.

Eduardo.
