Different Types of Smart Cards

      Three   different types
            Contact Card
          Contact less Cards
          Combination Card
                   Contact Card

   The most common type           Example
    of smart card. Electrical      USD laundry card
    contacts located on the
    outside of the card
    connect to a card
    reader when the card is
                 Contact Less Card

   These are smart cards that          Example
    employ a radio frequency            retail stored value, since
    (RFID) between card and              they can speed-up
    reader without physical              transactions and not lower
    insertion of the card. Instead       transaction processing
    the card is passed along the         revenues (i.e. VISA and

                                         smart cards.
                 Combination Card

   These are hybrids that             Example
    employ both contact and            An example card is a SIM
