on Europe there is talks about using Spanish's Bizum as the oficial European replacement for Visa/MasterCard

It's not a replacement until they issue cards that work without a phone.

Frankly, the number of people that care about no-phone functionality is tiny. I bet the greatest preference is the other way: the ability to use it without a physical card. Everyone has a phone.

Of course you need a backup at some point, but it’s just that: a backup.
