Custom APDU structures for Mifare

[Whizz]

Hello, I'm currently considering to use MIFARE based contacless card as drop-in replacement for our Java Card (ISO 14443-A and ISO 7816-4)

For that purpose I want the MIFARE card to mimic/emulate the APDU command/response of the Java Card. Our current implementation acquire data from The Java Card by sending a SELECT applet APDU commands followed by another APDU commands to get a data inside the card. It's all read-only. The data are static too.

So is this possible with MIFARE card, custom APDU structures to read static data inside the card?

Thanks

Hello,

MIFARE DESFire EV1 supports ISO7816 file System and a basic handling of ISO7816 Standard APDUs like SELECT and READ-BINARY. You may have a look in the datasheet for details about this. Probably that would allow you to replicate your application (provided you don't use encryption or secure messaging).
However, if you're currently using custom APDUs within your Java applet, such APDUs won't be understood by a DESFire EV1.

Best regards
