Patent abstract
A method and apparatus for accepting a pass code such as a personal identification number (PIN) are disclosed. The method involves providing a user with a challenge, typically on some form of shielded display to prevent third party viewing. The user now enters a response which transforms the challenge into the pass code allocated to the user. The response allows the user to be validated against a stored record of the pass code allocated to the user.
