Transactions Fail to Process
Check the Magnetic Card Reader:
1. Perform a test transaction using one or more different magnetic stripe cards to ensure that
the problem is not a defective card;
2. Ensure that you are swiping the card properly;
3. Process a transaction manually using the keypad instead of the card reader. If the manual
transaction works, then the problem may be a defective card reader.
Check the Smart Card Reader
1. Perform a test transaction using several different smart cards to ensure the problem is not
a defective card.
2. Ensure that the card is inserted correctly.
3. Ensure that the MSAM cards are properly inserted in the slots and are properly secured.
