How the payment process works

Here’s an overview of what happens behind the scenes and the different players involved

Step 1: The customer pays with Mastercard

The customer purchases goods/services from a merchant.

Step 2: The payment is authenticated

The merchant point-of-sale system captures the customer’s account information and securely sends it to the acquirer.

Step 3: The transaction is submitted

The merchant acquirer asks Mastercard to get an authorization from the customer’s issuing bank.

Step 4: Authorization is requested

Mastercard submits the transaction to the issuer for authorization.

Step 5: Authorization response

The issuing bank authorizes the transaction and routes the response back to the merchant.

Step 6: Merchant payment

The issuing bank routes the payment to the merchant’s acquirer who deposits the payment into the merchant’s account.
