Check Smart Card Reader
• Perform a test transaction using several different smart cards to ensure the
problem is not a defective card.
• Ensure that the card is inserted correctly (see Magnetic Card Reader Use).
• Ensure the MSAM cards are properly inserted in the slots and are properly
secured (see
MSAM/MicroSD Cards).
• If the problem persists, contact your local Verifone representative.
