Systems like these are very common in Europe. Here in Norway, you can pay for almost anything, anywhere with Vipps. It works very similarly to Brazilian Pix. Another system I have used in the past is the Portuguese MBWay which although similar to Pix and Vipps, doesn’t seem to be as widely adopted as the former.

The problem is that most European schemes are country specific. As soon as you cross the border even to another European country, your options are pretty much cash or Visa/MasterCard.

Interestingly, I've spotted a few places in Portugal already accepting Pix as a form of payment, catering to a large demographic of Brazilian immigrants and tourists.

I don't think I know a single person that doesn't have MBWAY, but I'm younger than 30, so that might have something to do with it.

Even then, everywhere you go, unless they're really small or old places that still don't accept anything other than cash, you can pay with MBWAY, through a QR code or NFC. All POS terminals support that nowadays. You can even add an email address and VAT number and newer terminals automatically skip printing the customer receipt, send it to your email and give the VAT number to the merchant (not entirely sure how that last one works, but it's there).

Interesting these platforms have existed for so long now (MBWay from 2014 and Pix 2016 if I’m not mistaken). I recall, back when it was launched, explaining it to friends in other countries (ie. UK) how good it was, not only the seamless payment network shared with friends, but also to be able to spin virtual cards with fixed value for online payments, and getting a puzzled reaction, “is that even legal?”

Vipps and MBPay are a pale shadow of Pix. No aliases, no mandatory participation, much lower merchant fees, and instant settlement not dependent on the merchant bank.
