Interface with Chip and Pin Payment Terminals for customer-present transactions, including retail and trade counters.

With the Opayo ePOS Payment Processing module, your axis diplomat system can interface directly with Chip and Pin devices. The correct transaction amount is passed directly to the device so there is no re-keying of amounts, ensuring error-free operation. A unique Transaction ID is returned, simplifying statement reconciliation.

Opayo are PCI DSS Level 1 compliant. Their PIN pads are PCI PTS 3.0 certified and use advanced encryption to ensure cardholder data is always protected.

Opayo Payment Terminal solutions are used by a number of well-known High Street names:



How It Works

axis diplomat passes details of required payments to the payment terminal via a web service. These payments may be originated from the following axis diplomat functions:

  • POS Invoice Entry
  • Sales Order Processing
  • Customer Enquiry (Statement tab)

Once the payment has been processed in the conventional manner on the payment terminal, transaction information is passed back to axis diplomat (again via the web service). axis diplomat will generate customer receipt transactions and, where an invoice is in context, allocate the payment

No card information passes through, or is stored by, axis diplomat at any stage in this process thus avoiding axis diplomat being within scope for PCI DSS compliance.


By communicating directly with the Payment Terminal, axis diplomat is able to pass the correct payment information to the device. This not only helps avoid human error when keying the amount directly into the terminal but also results in a more efficient checkout process and fewer delays for the customer.

Transaction ID information is automatically imported back into axis diplomat from the Payment Terminal.

This massively simplifies the statement reconciliation process and customers have reported an appreciable real-world saving, reducing the time taken for reconciliation to one quarter of the time previously spent reconciling point-of-sale card payment transactions.

By holding the Transaction ID within axis diplomat, the refund process becomes much simple and the process of reconciling refunds again becomes much easier.

Payment Terminals may be connected via the 3G/4G mobile network. This means that it is possible that your local network may be taken out of scope for the purposes of PCI DSS compliance.
