This article shows how to hide / show brands AMEX VISA MASTER or DINERS in the CopyAndPay card widget. This is in the event that you are not offering this to your customers.
By default MASTER and VISA are enabled on your Peach payments setup. AMEX and DINERS require additional setup with Nedbank (Please note as at December 2017, AMEX and DINERS are not available on Peach Merchant accounts. Contact email@example.com to discuss options)
