Which definition fits best with 'Credit Authorization'?

The correct definition of 'Credit Authorization' aligns with the process of checking the sufficiency of credit balance. This process is essential in transactions involving credit cards, where a merchant seeks approval from a credit issuer before finalizing a sale. During this authorization, the credit card issuer verifies whether the cardholder has the available credit limit to cover the purchase amount. This step safeguards both the merchant and the consumer, ensuring that the transaction can be completed without financial risk.

Additionally, while the transaction might also involve limits set by the credit card company, fees, or reports of credit history, these elements do not capture the essence of 'Credit Authorization.' The crucial factor is the verification process determining whether the consumer has enough available credit to proceed with the transaction.
