I am working with a client who is trying to run his Xamarin code on a Motorola TC70 handheld android device.
The customer is trying to use Xamarin to develop his code since he has a c# Windows desktop application that works with DesFire EV1. Thus far, he is unable to get his Xamarin code to successfully authenticate the DesFire EV1 card.
Do you have Xamarin sample code or can you provide xamarin-based documentation that can demonstrate how to perform authentication with DesFire EV1?
