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).

Now you know! :)
