Transaction Fails to Process

Step 1: Check the magnetic card reader

Step 2: Check the smart card reader

Step 3: Check the cable connections

No Response From the Stylus

The following are the corrective steps to be taken if the terminal does not process the transaction.

There are several possible reasons why the terminal may not be operating correctly or processing transactions. To check the most likely causes, follow the steps below.

1Make sure that you are swiping cards correctly with the MX800 Series terminal. For the MX800 Series terminal reader, the black, magnetic stripe on the card should face down and towards the screen.

2Perform a test transaction using several different magnetic stripe cards to ensure that the problem is not a defective card.

3Process a transaction manually using the screen instead of the card reader. If the manual transaction works, the problem may be a defect in the card reader. Contact your VeriFone distributor or service provider.

4If the manual transaction does not work, proceed to Step 3: Check the cable connections.

1Make sure you are inserting the cards correctly with the MX800 Series terminal smart card reader. The chip on the card should face down and inward.

2Perform a test transaction using several different smart cards to ensure that the problem is not with the card.

3Ensure any MSAM cards are correctly inserted and that the cardholders are properly secured.

4If the problem persists, contact your VeriFone distributor or service provider.

1Ensure that all cables are correctly connected.

2If cables are connected properly, check that the cable is in working order by connecting a known good cable. If transactions process with this cable, replace the defective cable.

3If the problem persists, contact your local VeriFone representative for assistance.

The following are the corrective steps to be taken if the terminal does not respond to the stylus inputs. (This procedure does not apply to the MX830 terminal without touch screen.)

3If the problem persists, contact your local VeriFone representative for assistance.
