desfire with 4 bytes?

just a question. pm3 identifies with hf search and also with hf 14a info my tag as a desfire but hf mfdes claims not to be a desfire because it has 4 bytes only but a desfire should have 7 bytes.
what went wrong?

Re: desfire with 4 bytes?

are you sure it is a Desfire?  It usually says a number of different possible tags with 14a info.   Like MFP (Mifare Plus) etc..

NXP MIFARE DESFire 4k | DESFire EV1 2k/4k/8k | Plus 2k/4k SL3 | JCOP 31/41   

How about you look at the Mifare Plus commands...
