1. Verification
The Issuing Bank, that is, the buyer's bank, verifies that the payment details are valid and that there are sufficient funds in the bank account or card to process the payment, including through the CVV or CVC, for example.
2. Authorization
If everything checks out, the payment service provider authorizes the payment. This is one of the most important steps in the transaction. If the transaction is approved, the amount is caught or reserved for the merchant in the customer's payment funds. This process takes only a few seconds.
3. Settlement
Once the transaction is authorized, fees are charged to process the payment, and it is processed. The selling party's bank then receives the funds, and deposits them into the merchant's bank account.
