I'm baffled. In Germany, the chipTAN method [1] [2] is pretty standard, which uses the bank card as a cryptographic element. And usually, German IT seems to be years behind the industry standard (e.g. I don't know a popular German e-mail provider that offers 2FA.)
[Edit] This is the best thing about chipTAN: Even if the computer is subverted by a trojan, or if a man-in-the-middle attack occurs, the TAN generated is only valid for the transaction confirmed by the user on the screen of the TAN generator, therefore modifying a transaction retroactively would cause the TAN to be invalid.

- ay 12y agoSo the chipTAN generator reads the details of the transaction optically, and then you just confirm them ? Pretty clever. On my chipTAN (Belgium, ING) I have to enter the number by hand (part of the account# of recipient, amount). On the positive side mine does ask for a PIN before generating the TAN, so is probably a bit more secure (balanced with a wear of the keys on the TAN generator, of course - so it is arguable which one is better)
