Remarks:
Mifare DESFire cards utilize a complex but flexible cryptographic protocol and require authentication,
session setup etc. and offer optional data encryption or message integrity checking. The protocol is not
implemented in the reader itself, but a library is available on request, which implements the protocol
and allows read/write access via the CCID firmware using the transparent data exchange.
Transparent data exchange for ISO15693 tags allows implementing features exceeding the reader-
supported read/write access in the host software. A library implementing further features is available
upon request.
Notice that ISO 15693 tags with eight-byte data blocks (e.g. Fujitsu MB89R118) require at least CDC
version 1.16 or CCID version 1.02 to read data blocks. Previous firmware versions were affected by a
bug. The bug did not affect writing.
