What is a Pre-Authorization?

Understanding Pre-Authorization in E-commerce

Quick Definition

Pre-authorization is a payment processing technique where a merchant temporarily holds funds on a customer's credit or debit card before finalizing the transaction. It verifies card validity and available credit without immediately charging the full amount, commonly used in industries with variable final costs like hotels, car rentals, and online services.
