Credit card processing cyp1h95

From GunGame5 Documentation

A payment gateway is an e-commerce application merchant account services provider that authorizes payments for credit card processing for online businesses, online retail merchants, pos systems, or traditional brick and mortar establishments. It is the equivalent of a physical point of sale terminal located in any retail outlets. Payment gateways protect credit card processing details by encrypting sensitive information, such as credit card, checking account and debit card numbers, to ensure that information is passed securely between the customer and the merchant and also between merchant and the payment processor.
