I think you really need to make a card that isn’t a Visa or MasterCard or a QR payments system that’s wired to common banks. I don’t think anyone has suggested creating a payment processor without this, because the issue is with Visa/MasterCard, not with the middleman.

I think Valve could actually find a bank to work with to run a QR payments scheme for the gaming industry (SteamPay perhaps?) that’s “topped up” via ACH. Just ignore the whole card part, since it’s online you don’t even need it. Require biometrics and you can make the fraud burden easier.

Of course this would cost a lot of money, but it’s at least in the realm of possible versus a PayFac etc.
