Abstract
An improved method for verifying the identity of a prospective terminal user presenting an identification card or a credit card and a memorized personal identification number. Only part of the information necessary to correlate an account number to a personal identification number is available at any accessible place in the operating system. Neither the credit card, the host computer, nor the transmission link will ever have sufficient information to completely correlate an account number to a personal identification number.
