  • Computer product and method for smart card
    Patent number: 6772239
    Abstract: A system, method and computer program for smart card with memory is disclosed. A very low cost approach to embodiment is disclosed, making use of a micro-controller with a FLASH memory or a WORM memory. An approach to programming a flash memory under the control of instructions within that memory itself is disclosed. In utilizing the invention, it is possible to build smart cards at a lower cost than heretofore.
