I was hoping more banks would introduce support for U2F. In Europe ING was one of the first if not the first, but so far few followed.
That's for logging into the app. What I mean is using NFC for payments.I have ING but they also moved away from supplying their own NFC payments in favour of using Google Play, sadly.
I checked and I can set one of my banks as the "default wallet app". I guess there are still some holdouts left.
