In payment processing, both a payment processor and payment gateway are essential parts of the process. Yet many people are often unclear about the difference between the two.

Usually, a payment processor is the service that communicates between the merchant, acquiring bank, and issuing bank. When a purchase is made by a customer online, that customer presents a payment card for their transaction. Payment processors validate the authenticity of this payment card and alert the customer’s bank of the transaction request. Once the transaction is approved by the issuing bank, the payment information is sent to the acquiring bank or other third-party account that accepts customer funds.

Meanwhile, payment gateways are software that allow payment processors to do their job securely. When customers put in their payment and bank information, the gateway is responsible for safely transporting this information to the payment processor. Gateways also handle information sent by the payment processor once a transaction is approved or denied, and verifies the validity of the card used. Some payment processors offer payment gateway software to clients, but this isn’t universal.
