Since mobile "App"-based wallets seem to be the core of commercial activities in
this space an important task ought to be finding ways to connect those to the Web
although the W3C has turned a blind eye on the App phenomena:

True.

Yes, but Internet connectivity differs from BLE and NFC since it is not only
depending on the device but on radio conditions and data roaming. It would IMO
be a disadvantage mandating Internet connectivity (on the user-side), unless it
is absolutely necessary in order to perform a transaction.  For the mobile wallet
NFC/BLE scheme I outlined, it may indeed be possible getting away from Internet
connectivity without crippling functionality.

What the "backup" solution will be is an interesting question.  It might
be cash as well. We'll see...
