This is not a wallet (the name is a bit confusing). Wero (like iDEAL, which it is partly based on), is an online payment system directly backed by your bank account. This is an app that uses the Wero system for doing P2P payments (like Tikkie in The Netherlands).

Most likely, Wero (like iDEAL) will also support alternative apps for P2P payments.

Also, Wero will support in-store payments in the future, making Google Pay/Apple Pay unnecessary [1] unnecessary, which is a big win.

[1] Strictly spoken it's unnecessary now as well, but then each bank needs to implement its own NFC app and most simply opt foor Google/Apple Pay.

I think most/many banks had their own nfc tap-to-pay solution before Google/Apple Pay came along. Any idea why the banks chose to give that up?
