What does CAP stand for in transaction processing?

The correct interpretation of CAP in transaction processing is "Central Authorization Process." This term refers to the systematic approach used by payment processors to verify and authorize transactions before they are completed. This process is crucial in ensuring that the transaction can proceed without issues, such as insufficient funds or fraud. The Central Authorization Process serves as a centralized system where transaction requests are routed for approval, helping to streamline operations and enhance security in payment transactions.

Understanding that "Central Authorization Process" is key to transaction integrity and preventing unauthorized transactions helps solidify the foundation of transaction processing within the financial ecosystem. The other interpretations do not pertain directly to the authoritative framework required for transaction approval, which is why they do not accurately represent CAP in this context.
