Hah, we have a payment processor here in Germany called &quot;Sofortüberweisung&quot;.<p>It works like this: When you want to pay for something you give them your login credentials to your bank account and a TAN and they send the money to the merchant for you.<p>The selling point of this service is that SEPA wire transfers usually take one day. But with their service the merchant gets an instant notification of money received and you can get your stuff one day earlier.<p>It&#x27;s crazy but people use this and have no problem handling over the keys to their bank account.
