When will American banks begin to use BankID?

Been reading up on a system called BankID, implemented by Norwegian banks. It's a type of computer chip which contains a random number generator (RNG). They don't publicize the source code, but it bears some resemblance to gambling software.

You set your own PIN code, which must be typed in to retrieve the unique bank-code (changes each time). This may sound confusing at first, but the system is rather clever.

1. You first type in your social security at the bank's log in page. 2.It then asks for your PIN code on the "BankID chip", which in turn provides you with a RNG code. 3. You then finalize it by typing in a personal password on the log in screen.. And voilá.

They also changed it from an all-Java system, to a html5 infrastructure. Apparently it can also be installed on a cellphone.

I really love this device and wish my US bank could offer something similar, besides normal Google 2-FA. The best feature though is this...

Apparently people can also sign loan papers and official documents as if it was a legalized contract. How cool is that? No more paperwork.

We need something like this in the US.

What do you guys think?
