Abstract
A verification system is disclosed in conjunction with a card having a uniqueness characteristic for avoiding counterfeits. A magnetic stripe on the card records encoded combination data based on the uniqueness characteristic and personal identification data of the assigned bearer. The card is sensed to provide fresh observations of the uniqueness characteristic along with data from the magnetic stripe. An operator interacting with the system provides his personal identification data. The magnetic stripe data is combined with the operator-provided personal identification data to derive a decoded indication of the uniqueness characteristic. Such a uniqueness characteristic is compared with the freshly sensed uniqueness characteristic as a basis for verifying the authenticity of both the personal identification data and the card. The system further incorporates structure for modifying the personal identification data by interaction between the system and a proper operator.
