For this purpose, a centralized database has been created in the system, through which users are identified. The mechanism of execution of any payment in the Instant Payments System starts from the customer and ends in the CustomerB. That is, the difference from traditional payment systems is that the process from customer A to customer B is complete. In traditional payment systems, the processes are not complete, i.e. transactions are not settled immediately.
As a result, the funds are not immediately available to end users. In the case of payments processed through the Instant Payments System, interbank settlements are made in real-time, and the funds are immediately reflected in the accounts of end users, i.e. individuals, legal entities, businesses, as well as banks.
