Hi,
I am communicating directly with the card via Scard api for Windows, no framework used. I need to know the specification for the ChangeKey command and the CRC algorithm used.
I have the specification for MF31C40, but actually have a MF3ICD81 EV1. How do I get hold of the following specification: MF3ICD81 MIFARE DESFire EV1_3.6?
Regards,
Warren
