A payment processor is the company that carries a card payment's details between the business, the card scheme and the banks. It gets the payment approved or declined in seconds, then makes sure the money is settled to the business later.

Where it sits

  • The gateway collects the card details securely at checkout.
  • The processor sends them through the card scheme to the customer's card issuer.
  • The issuer approves or declines, and the answer comes back the same way.
  • Later, the processor and acquirer settle the money to the business.

Processor, gateway, acquirer

The gateway is the front door, the processor moves the messages, and the acquirer is the bank that holds the merchant relationship. Many providers bundle all three, so a business often only deals with one company.
