Payment Methods
What is a payment gateway? Why do I need a merchant account at an acquirer?
A payment gateway or Payment Service Provider (PSP) is a service that processes credit card payments for online merchants.
Payment gateways facilitate transactions by transferring key information between payment windows and the front end processor/bank.
