This payment method’s configuration can be done on the **Payment Options & Add/Edit POS/Card Setting** pages on Omnitron. After the settings are completed, it will be accessible under a new tab on the checkout payment screen as it is a credit card type payment integration. Bin number must also be configured. For additional information, refer to the [POS Integrations](/tutorials/omnitron/sales-channels/payment-management/how-to-manage-pos-integrations-in-omnitron.md) tutorial.

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

* There can be 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.
* This integration is compatible with Masterpass. The document can be referenced: [Masterpass REST POS](/technical-guides/3rd-party-integration/masterpass-integrations/masterpass-rest-pos.md).
* To use version 3 hashing, the bank side should define the merchantName value with English characters. It should not have Turkish characters. Faulty value example:
  * "merchantName": "AKINON.COM"
