How MIFARE Uses Cookies

[Daniel Tran]

Thanks! But my issue is the Crypto mode show incorrect and I want to read key settings from TagInfo as well. Tt must show as AES after changing key from 3DES to AES. Can you try to change the PICC key from 3DES to AES and read the key settings in the TagInfo app for Desfire EV1 card? //It still shows as DES key type after changed to AES. It works well for Desfire EV2.

Hi Taplink Support,

Thank you for your info! However we can read the key info settings anymore in the TagInfo andoid app after updating the bit for "free directory list access without master key" to zero in the ChangeKeySettings command. See attached files for details.

Thanks

Hi Taplink Support,

I have the same issue as Anmol. After changing the PICC key successful from default key (2K3DES) to custom key (AES), but it still shows DES key when checking by the TagInfo android app. However the custom key works fine when re-authentication. // The same code it does not work for Desfire EV1 but works for Desfire EV2.

byte keyNo = (byte) 0x80;
byte keyVersion = 0x00;

Thanks
