Last year I got to see a prototype of the new OTP tokens which fits into a regular plastic credit card. I still wonder how they managed to put a battery there (and how long it will last). This is a very neat product. In terms of usability, this token has a higher chance of being popular with online bank users since we all carry at least one credit card at all times. It is easy to use and carry. The key is to make sure the battery lasts till the card exprires.

With the card, consumers logging on to an online bank account, for instance, would type in their regular username and password, along with a six-digit code that appears on the card’s display window. That code constantly changes, meaning the customer needs to have possession of the card to access the account.”
