The payment process typically involves the following steps:
The customer initiates a transaction by entering their payment details. The payment processor sends the details to the card network (e.g., Visa, MasterCard). The card network forwards the details to the issuing bank for authorization. The issuing bank checks the customer's account for sufficient funds and either approves or declines the transaction. The response is sent back through the card network to the payment processor, and finally to the merchant. If approved, the funds are transferred from the customer's account to the merchant's account.
