When a card payment is made, the authorization process involves the merchant sending the transaction details to the cardholder's issuing bank. The issuing bank then verifies if the cardholder has sufficient funds or credit available to complete the transaction. If approved, the issuing bank sends an authorization code back to the merchant, allowing the payment to go through. This process typically happens in real-time, ensuring a quick and secure transaction. **
