چکیده
The underlying model of an electronic payment system consists of three parties: a bank, a customer, and a shop. There are three different types of transactions within the system: withdrawal involving the bank and the customer, payment involving the customer and the shop, and deposit involving the shop and the bank. The customer's account is debited during withdrawal, and the shop is credited during deposit. The three transactions take place simultaneously or separately, depending on the payment system.
