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
    inserted.
                 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
    exterior of the reader and           Mastercard), like traditional
    read.
                                         smart cards.
                 Combination Card

   These are hybrids that             Example
    employ both contact and            An example card is a SIM
    contactless technology in           card for mobile GSM where
