In the future, sure. I’d love to see PayM support.
PayM requires current accounts first, it’s essentially just a lookup service between phone numbers and account numbers/sort codes with actual payments happening over an existing method (of course, Faster Payments are heavily preferred).
Take a look at the old P2P payments thread for some further insight from the team in to the pros and cons of PayM itself.
