I thought that chip-in EMV was bad until I saw some of the stuff coming out of Discover cards for contactless EMV. Buying a test card set from somewhere like B2 Systems was very beneficial even just integrating an EMV reader from a hardware device to a payment processor.

The problem is that the contactless stuff is all custom per network.

Some of the implementations are reasonably close to contact EMV; others might as well be a completely different stack and technology.
