I am trying to read the Mifare DESFire EV1 card using HID iClass DESFire EV1 reader and same reader module installed on Coppernic PDA Device C-One.
So I wanted to know the reason behind this, it is due to Card or due to reader.

IC Type:- MIFARE DESFire EV1 (MF3ICD21)
DESFire Applications:- Type 4 Tag version 2
ATR string from two different manufacturer reader
1) Omnikey Reader 5427 CK :- 3B 81 80 01 80 80
2) NFC enabled device: 0x0675778102800
3) Coppernic C-One device:- 75 77 81 02 80
Please check and let me know where exactly the problem is?
