What Is a Payment Gateway? 

A payment gateway is an interface that collects, encrypts, and authenticates customers’ payment information.

To break it down, when customers enter their payment details – such as card information – to make a purchase, the gateway verifies that data and proceeds to the payment processor and then to the business owner’s account upon approval. If there is a discrepancy, the funds stay with the customers. 

If you’re considering joining the booming UK ecommerce market, you need to have payment gateways that cater to UK online transactions in place. 

That said, the ideal gateways should accept the UK’s popular online payment methods, including credit and debit cards – with Visa, Mastercard®, and Amex topping the card chart – and PayPal.
