Occasionally you may have card terminal error messages on your machine, and whilst our technical team will always endeavor to support customers on this, some prefer to understand what these card terminal error messages mean and how they impact their business.
If you are attempting to process a payment, and you receive the card terminal error message “Do not honor” – the issuing bank is preventing the transaction from being authorised, and instructing you (the seller of the item) to not honor the card. In a situation like this, we would recommed getting the customer to phone their bank directly and question why the payment was declined. Once the issuing bank confirms this, you can attempt to try the transaction again. Alternatively you can ask the customer to try an alternative payment card.
A communication error can occur for several reasons. GPRS/GSM terminals are reliant on a mobile signal and this can be as a result of the network going down within a certain area or location. In situations like this, the transaction that the customer is attempting to process will void and display a diagnostic code at the bottom of the till roll with either ‘41414141’ or ‘82828282’. These codes specifically relate to the GPRS units, and we have a few procedures on how to rectify this. We would recommend you switch off your card machine and leave the unit for a minimum of 30 seconds. Remove the roaming sim card from the device, and gently wipe the metal chip on the sim. Replace the sim and then turn the terminal back on. Leave for an additional 2-3 minutes and see if the card machine is displaying any of the following – GPRS, Network Bars and a Network. If this fails, please select a network manually. If the card terminal error message persists, please contact a member of the technical team.
