It is the equivalent of a physical point of sale terminal located in most retail outlets. After a online customer has entered credit card/bank details the payment gateway encrypts the data and passes it securely between the website and the merchant and also between merchant and the payment processor. Many retailers may already have a payment gateway and simply need to configure it to allow for online payment processing.
Echo Media is a preferred partner of Realex Payments who are one the fastest growing payment gateway providers in Europe. We also have experience with SagePay, Stripe etc.
