Experience

  • Patent: Secure Loyalty Card System
    http://www.ipo.gov.uk/p-ipsum/Case/ApplicationNumber/GB1108567.7

    This invention provides a data card for use in a consumer reward or loyalty incentive program, wherein the card comprises an input for receiving loyalty/security data.

    It also secures it in an innovative way. There is a data card reader, server, and method of authenticating the data on the data card using digital cryptographic techniques—so that the data card is still fully readable and writable at an insecure location, but protected so that a hostile cardholder cannot insert or modify the data to compromise the integrity of the card, nor duplicate the data to reuse it for his own benefit.
