I am trying to integrate Visa Tap to Phone for a Android mobile app. I'm getting stuck on figuring out how the Visa Contactless Kernel SDK for TTP is supposed to be implemented. The sample testTTP app is working but I don't understand how to start testing or modifying it. My questions are:
1. How do I tell if the card is scanned?
2. What API's / SDK's does a complete solution require? Is their more than the Visa Contactless Kernel SDK that I need?
3. Is their more sample code that I can look at to understand how Tap to Phone works, or an example of an app that I can look at?
Anything that helps me get started integrating Tap To Phone in an Android app would be appreciated.
