As someone who has bank accounts in Europe (I am a foreign national working in the US) I can tell you that bank security in The Netherlands is standard two-factor authentication. My "chip and pin" card contains the standard mag stripe along with an embedded microchip that can be used with chip transactions. Along with that i got an "e-Identifier" which is a stand alone device. When I go to log into my bank I type in my account number (listed on my card), the card number (listed on the card) and then click next. On the screen will be a series of numbers that I then have to type into my eIdentifier. So I slide my card into my eIdentifier and type in my pin number (what I have + what I know) and then type in the number presented to me, it then spits out another random number, I fill that in on the web form that the website provided to me. At that point I am logged into my banks website and I can look at my transaction history, and everything along those lines. If at some point during that time I want to transfer money or do anything else that affects any part of my account I once again have to enter in my pin and go through the same steps as before to login on my eIdentifier. This provides security for me. I never type a password into any part of the website, the codes are one time use only, and even if someone were to come to an open session and attempt to use it to transfer money in or out of the account they would be required to have my card, pin number, and an eIdentifier. I'm a big fan of systems like that, it provides me with much more security than anything else, including "I wish it were two factor authentication" that American banks provide (look at this picture, now provide us a password). What Blizzard is doing is considered standard security practice in Europe and other countries where banks are more stringently controlled and regulated and fraud is not taken lightly, and the only real new "innovation" if one may even call it that is that a online computer game is using this mechanism.
