Yeah it’s a bank, and most banks do not support NFC payments in their apps, you need Google Pay or Apple Pay. Revolut is not listed in the available payment apps.
The closest thing I’ve found regarding this is this community request which still hasn’t been resolved https://community.revolut.com/t/support-nfc-functionality-directly-in-the-revolut-app-for-android-without-google-pay/191216
Last time I opened a new Google account ~2019 I noticed if you did it from some countries it didn’t ask for a phone number (even on a vpn). I remember Greece and Romania being two of them. It’s been a while since then but it’s worth a try. But you also had to receive an email within a few a hours otherwise it asked for a verification. This was all through trial and error so take it with a grain of salt of course.
Interesting, based on similar threads I was under the impression most banks didn’t support NFC payments without Google Pay. Sadly no banks here have their own NFC payments. My bank used to have it but then removed it for some reason.
