CCV, EMS and NMI are updating their gateway processing platforms, requiring a change in how the Payter terminals communicate with them.
On 14th October, Payter released P6x firmware v2.16.57. This release contains the critical changes to the host integration with the CCV, EMS and NMI platforms, as well as performance improvements.
An update to the firmware of your terminal is required to continue to communicate with the platforms. Terminals that have not been updated will stop processing payments when the changes at the platforms take effect, this could possibly be within weeks. Exact dates have not yet been confirmed by the platforms.
What will happen All P6x terminals will be updated automatically between Monday 9th November and Monday 30th November, during the night. You do not need to take any action. If you prefer to update your own terminals Email support@payter.nl before the 5th November. They can exclude your terminals from the automatic rollout. You will then be responsible for deploying v2.16.57 yourself, accepting the risk of transaction failure if not completed in a timely manner.
