As you know MIFARE Desfire EV1 is the next generation of MIFARE Desfire with some features improving security.
Then is there any compatibility between commands used for communicating with Desfire & Desfire EV1? Does Desfire EV1 answer to APDU commands written for Desfire? Specifically consider security related commands (except AES related commands, as I know those were only added in Desfire EV1) and file access.
