> Hopefully the same app will work there...
That's the problem: currently many of those banking apps in the EU require having a phone with Google Play services and other "security" stuff that makes you reliant on American companies, like the post you're replying to claims.
Now that the cat is out of the bag, I am confident that those banking apps will (eventually) work without the likes of Google Play Services. Additionally, what i really want is an alternative to Visa/Mastercard, meaning I can use it for renting a car or paying online.
