What is a “payment gateway”?

A payment gateway is a transaction service that authorises credit and debit card payments for businesses, online retailers and service providers, etc. It establishes the connection between your website or payment terminal and an acquirer to complete the transaction. Payment gateways are necessary for making any kind of payment transactions.

Payment gateways protect card details by encrypting sensitive payment information, such as the card number, to ensure that information passed between the customer, merchant, and acquirer remains secure.
