Yeah I like the app I just didn't understand it at the time that I purchased it and got myself anbut as I understand it a little bit better now and what was going on to the national security prep list and being a national security agent on how revenue works an ignorant mistake I made know what you're doing if you're operating it.

Like the other app, we need the functionality of acr 122 with it. Why we can't connect it with this app?

Thank you for your comments. The libnfc library cannot work on Android directly, I'm still working on it with the original android protocol.
