"The value of smart cards is that in addition to storing information, they can process data and execute small programs," said Dr. John Butterworth, chief scientist, Security Sciences International, Redondo Beach, Calif.
Manufacturers have numerous applications for these microchip-enhanced wonders. For instance, at universities smart cards have been used to identify students, maintain financial, library, grade and attendance information and provide building security.
