In fact the system used by the major Dutch banks is audited rather extensively. The OTP system is based on an external smartcard reader and a smartcard application on the bank card. They have no physical connection so the web interfcae will present you with a challenge and you must use that challeng, your card and your pin to generate the proper response. Then you have to type in this response.

It is a combination of:
 - What you have (the card with the smartcard application)
 - What you get (the challenge from the server)
 - What you know (your pincode)

A few banks in Australia are using a similar idea: Bank of Queensland offer a device that every time you press a button it gives a code that their website expects in addition to your net banking username+password. Commonwealth Bank do the same thing but instead of a device they do a 2 stage login, first stage being username+pass the second being a code sms'sed to a pre-registered mobile phone number.
