# Payment card codes {#en_card_codes}

A reference with the internal codes indicating the payment card brands that can be used for working with the platform.

When you work with different interfaces of the Ecommpay payment platform, you may need to use specialised codes to indicate the card [brand](en_glossary.md#) while processing card payments. In particular, such codes can be passed in requests for opening Payment Page with the preselected card brand\(specified in the `force_payment_method_subtype` parameter\) and callbacks. In addition, the information about card brands is shown in Dashboard. These codes are listed in the following table.

|Code|Brand|
|----|-----|
|`amex`|American Express|
|`maestro`|Maestro|
|`mastercard`|Mastercard|
|`visa`|Visa|
