## <mark style="color:red;">Additional Notes</mark>

* There can be a maximum one credit card (or Masterpass) payment option per sales channel in Omnitron but POS integrations connected to the payment option can be multiple for different payment providers.
* If NKolay will be used with Masterpass for 3D Purchases, empty value should be added to Masterpass Allowed md statuses field.
* For additional information, refer to the [POS Integrations](/tutorials/omnitron/sales-channels/payment-management/how-to-manage-pos-integrations-in-omnitron.md) tutorial.
* [Masterpass REST POST](/technical-guides/3rd-party-integration/masterpass-integrations/masterpass-rest-pos.md)
