Transactions
Fail To Process
There are several possible reasons why the unit may not be processing
transactions. Use the following steps to troubleshoot failures.
Check Magnetic Card Reader
• Perform a test transaction using one or more different magnetic stripe cards to
ensure the problem is not a defective card.
• Ensure that you are swiping cards properly (see Magnetic Card Reader Use).
• Process a transaction manually using the keypad instead of the card reader. If
the manual transaction works, the problem may be a defective card reader.
• If the problem persists, contact your local VeriFone representative.
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 Smart Card Reader Use).
• Ensure the MSAM cards are properly inserted in the slots and are properly
secured (see MSAM / Micro SD Cards).
• If the problem persists, contact your local VeriFone representative.
