Payment Gateway

The payment gateway is a software and hardware complex that processes payments for financial services. It encrypts the processed data and is responsible for the correct authorization of clients.

The payment gateway only provides switching between the buyer and the seller. Payment systems are responsible for accepting funds.

In most cases, these are different systems, but large companies combine two services into one, for example, Paypal. It is a payment system and at the same time provides secure data transfer.

The principle of operation

The payment gateway works as follows. The customer orders the product in the online store and goes to the payment page. Then he enters the bank card details on the payment system’s website. The gateway transmits the received information to the acquiring bank.

Next, the bank sends an authorization request to one of the international payment systems (Mastercard, Visa). She confirms the payment by sending the authorization code through the acquiring bank.

At this moment, the user receives an SMS from the bank whose card the payment is made on. He enters the numbers on the website and receives confirmation of the successful operation.

The process itself takes a few seconds, but there may be delays. They occur due to the large number of simultaneous requests that come through the payment gateway.
