To solve the problem with Sofortüberweisung it would be enough if my bank would just provide a digitally signed statement, that I authorized a payment and had enough funds at the time so they would execute it. I could take this statement, show it to the merchant and he could verify it by using a publicly known publlic key of that bank. If nothing better is available it could be the key they us on their website.
I wonder who is interested not to already have this. I can't be the first person with that idea.
- blauditore 10y agoFrom what I understand, this is basically what happens for most online credit card payments. If you enter your credentials, you're redirected to a verification page by the issuer where you have to enter a password or SMS-sent key. On success, this page then passes a signed token (or similar) back to the original online shop as confirmation.
