This payment processor also communicates information from your customer’s card to your bank and the customer’s bank.

How Does Credit Card Payment Processor Work

Below are ways it works:

  • The customer or consumer starts a transaction by providing their card details at checkout.
  • Their card information will be sent through a payment gateway from the merchant which encrypts and transmits payment data to the processor.
  • Then the payment processor will send the card information to the card network like a Visa or MasterCard.
  • The card network then confirms with the issuing bank if the customer has sufficient funds in his or her account to make the purchase. After sufficient funds are available, the transaction will be approved.
  • The payment processor sends authorized payment data to the merchant through the payment gateway. Allowing the merchant to accept the payment and receive the purchase funds while debiting the customer’s account
