How does a payment gateway work?

You do not need to worry about processing your transactions. The Cardinity system will handle the process for you, and you will receive your funds.

  • Customer

  • Merchant

    Payment gateway

  • Merchant account, acquiring bank, card processor

    Card networks

  • Customer’s issuing bank

A payment gateway connects your online shop with your acquiring bank (and your merchant account). This process includes the following steps:
  1. A customer enters his personal and card data at the checkout and chooses to pay with a credit/debit card.
  2. Your website encrypts and sends the customer’s data to the gateway.
  3. Then, the data is transmitted further. It goes through the payment processor and the card associations (Visa and MasterCard) until it reaches your customer’s issuing bank for authorization.
  4. The payment gateway receives the response that the transaction has been approved and authorized and sends it to your website.
  5. The order is created, and the money is transferred from your customer’s bank account to your merchant account.
