Mastercard SecureCode does this. I'm seeing it more and more. My bank implements it using hardware 2fa; a separate dongle that reads my CC, asks for my PIN and a transaction salt (or QR scan) and computes some hash (?) from it.
It's actually very frustrating when I don't have the 2fa device on me.
- leni536 11y agoYeah, I know MasterCard SecureCode. I have two bank accounts, one bank implements it using 2fa and uses SMS as the second factor, still no need for the card. The other bank doesn't implement it at all. And you still have to enter your credit card info, while the actual authentication actually has little to do with it.
