 Ok, that would be an option.

One of the first things to explore is if its possible to dispatch
different isodep applications to different apps. I know you can add an
intent filter matching action=android.nfc.action.TECH_DISCOVERED and a
custom tech filter android.nfc.tech.IsoDep. However, as long as there
is no mime type or similar concept, apps will always fight for access to
IsoDep endpoints. We will want to avoid that situation.

I think maybe the way you do it is to have a NDEF tag that triggers the
app, and then that starts an IsoDep protocol once opened. I *think*.
