In some cases a chip is unreadable by the terminal, because it was damaged. In these cases the magnetic stripe on the card can often be read to complete the transaction. Here are the steps to complete the transaction after the card fails:

1. Leave the terminal device face down so that the pin pad and LCD are facing you.
2. Take the customer's credit card out of the Chip Reader.
3. With the card facing you (magnetic stripe down) swipe the card.
4. Turn the device over and present the signature screen to the customer.
