Introduction
Credit card authorization is a crucial process in the payment ecosystem where a transaction is either approved or declined by the card issuer. This procedure ensures the cardholder’s account has sufficient credit available, and the transaction complies with the card issuer’s fraud detection policies.
Historical Context
Credit cards emerged in the 1950s, but the authorization process we know today evolved alongside advancements in digital technology. Early methods were manual, involving carbon paper and phone calls to card issuers. Modern authorization is swift and mostly automated, powered by real-time data processing and sophisticated algorithms.
Types/Categories of Credit Card Authorization
- Pre-authorization: Temporary hold on funds before the transaction is fully processed (e.g., hotel bookings).
- Post-authorization: Actual deduction from the cardholder’s account following a pre-authorization.
- Real-time authorization: Instant approval or decline during an online purchase or at point-of-sale (POS).
Key Events
- 1950: Diners Club issues the first charge card, leading to the concept of credit card authorization.
- 1970s: Introduction of magnetic stripe technology facilitates electronic authorization.
- 1990s: Online shopping booms, driving enhancements in real-time authorization processes.
- 2010s: Emergence of contactless and mobile payments brings new layers to authorization protocols.
Process and Explanations
The credit card authorization process involves several steps:
- Initiation: The cardholder presents the credit card for a purchase.
- Data Transmission: Merchant sends transaction details to the acquiring bank.
- Verification: Acquirer routes the transaction to the card network (e.g., Visa, MasterCard).
- Approval or Decline: Card issuer checks account status, credit limit, and fraud indicators before responding.
- Response: Approval code or decline message is sent back through the network to the merchant.
