Help required. Unable to personalise,format, read and write to DESFire 8K card

[Ayitey Djaba]

Hello, I'm currently have a Samsung Galaxy S5. I'm using it together with the an 8K DESFire card to build an android app to create and store ID. I downloaded the lite version of the SDK and got all the code samples. However, anytime I try to personalise / authenticate with the card, I either get an authentication failed error or a wrong command error. I would appreciate it if I could get some help.

Best regards

Hi Ayitey,

You are sure that your personalizing steps are correct? Do you are able to execute the same steps for instance with a reader on a PC?
A code snippet of your sequence if very helpful to locating the error.

Kind regards,
The MIFARE Team
