ACCESS MIFARE DESF?RE EV1 W?TH ACR1281U READER

[akdrmrk]

Hi

I want to access mifare desfire ev1 4k..I am using for authenticate { 0xAF 0xA2 0x00 0x00 0x05 0x01 0x00 0x04 0x00 0x60 } , the software returned 90 00. so it can be authenticate with this APDU.

Then; I want to update block 4 with { 0xAF 0xD6 0x00 0x4 0x16 } . the software returned 1C 90 00

Then; I want to read block 4 with { 0xAF 0x0A 0x00 0x04 0x16 } . the software returned 90 00 and response 1C...it return 90 00 like true but don't read and what is 1C. I don't add it.

Thanks...

HI,

I'm afraid that DESFire card is not block-oriented, but file-oriented, reader is innocent.
It will probably be required to obtain documentation from NXP to DESFire (EV1) card.
