A payment gateway is a service that securely sends credit card information from a website to the credit card payment network for processing, then returns transaction details and responses from the payment network back to the website. Your online business needs a payment gateway if you accept (or want to accept) credit card payments online or on a mobile device. Think of it as the secure technology that provides a bridge between your business and your customer.
