In Estonia, you can link a phone number to your IBAN. When making payments, the sender just needs a phone number, and the corresponding IBAN is automatically looked up. (The lookup service is managed by the central bank, and used by all (major) banks.)

Same in Poland, thanks to BLIK payments. Works across all major banks. https://iko.pkobp.pl/iko_en/features/mobile-transfer/

There's a similar system in several country (Spain as well for example, called Bizum). It's a shame that it's not a Europe-wide system.

We have that here for Zelle, which is built-in to some banking apps, making it really easy for most people to achieve this. You can alternatively give them a name or email as well. Zelle is not perfect but I have used it often just because it is built-in to my banking. I just wish I could have multiple bank accounts hooked up to it properly, not sure how to sort that out.

The same exists in Spain (albeit with limits per month), it's called Bizum: https://bizum.es/en/about-us/
