Confirm Signature

Under certain circumstances (ie. customer does not enter a PIN or the card does not have a chip), a signature is required to verify the customer is the owner of the card. If the Quest+NAB app requests you verify the customer's signature, you need to get the customer to either sign on the screen of your device or on a printed receipt. Ensure that the signature provided matches the signature on the rear of the customer's card.

IMPORTANT: Should the signature provided not match what is on the back of the customer's card, select NO. The customer WILL NOT BE CHARGED IF NO IS SELECTED and you can provide the customer a receipt that indicates that the transaction has been declined due to a Signature Mismatch.
