4. Key Concepts in Credit Card Operations
4.1 Authorization
· Definition: The process of approving a credit card transaction.
· Process: When a cardholder initiates a transaction, the merchant sends the transaction details to the acquirer, which then forwards them to the card network. The network routes the request to the issuer, which verifies the cardholder’s account status and available credit. The issuer sends an approval or denial back through the network to the merchant.
· Result: If approved, the transaction amount is reserved against the cardholder’s credit limit.
4.2 Authentication
· Definition: The process of verifying the identity of the cardholder.
· Methods: PIN entry, signature, CVV (Card Verification Value), and more recently, biometric authentication (fingerprint, facial recognition).
4.3 Clearing
· Definition: The process of transmitting the transaction details from the merchant to the issuer for posting to the cardholder's account.
· Process: After authorization, the transaction details are sent through the card network to the issuer. This usually happens in batch processing at the end of the business day.
4.4 Settlement
· Definition: The process of transferring funds from the cardholder’s issuing bank to the merchant’s acquiring bank.
· Process: The issuer transfers the transaction amount to the acquirer, which then deposits the funds into the merchant’s account, typically minus the interchange fees and other costs.
4.5 Interchange Fees
· Definition: Fees paid by the merchant’s acquiring bank to the cardholder’s issuing bank for processing transactions.
· Components: These fees cover costs such as transaction processing, fraud protection, and cardholder rewards.
4.6 Merchant Discount Rate (MDR)
· Definition: The fee charged to merchants by their acquiring bank for processing credit card transactions.
· Components: The MDR includes interchange fees, network fees, and the acquirer’s markup.
4.7 Chargebacks
· Definition: The process where a cardholder disputes a transaction, leading to a reversal of the transaction.
· Reasons: Fraudulent transactions, billing errors, or disputes over the quality of goods or services.
· Process: The cardholder contacts the issuer to dispute a charge, and if the issuer finds the dispute valid, the transaction amount is refunded to the cardholder and debited from the merchant's account.
4.8 Rewards and Loyalty Programs
· Definition: Incentives offered by issuers to cardholders for using their credit cards.
· Types: Cashback, points, travel miles, and discounts.
· Purpose: To encourage spending and increase customer retention.
5. A Typical Credit Card Transaction
· Purchase Initiation: The cardholder presents the credit card to the merchant.
· Authorization Request: The merchant sends the transaction details to the acquirer, which forwards them to the card network and then to the issuer.
· Issuer Response: The issuer checks the cardholder’s account and responds with an approval or denial.
· Authorization Response: The card network sends the response back to the acquirer, which forwards it to the merchant.
· Clearing and Settlement: The transaction details are processed, funds are transferred from the issuer to the acquirer, and finally to the merchant’s account.
· Posting to Cardholder Account: The transaction is posted to the cardholder’s account, and the cardholder receives a statement with the transaction details.
6. Credit Card Networks
