What is a Payment Gateway?
A payment gateway is a technology used by merchants to accept debit or credit card purchases from customers. More than just a digital cash register, a payment gateway ensures secure transaction processing, facilitating the transfer of information between a payment portal (like a website) and the acquiring bank.
Key Functions of a Payment Gateway
- Authorization: Verifies if the customer's funds are sufficient and available.
- Capture: Locks funds for the transaction once authorization is complete.
- Settlement: Processes the actual transfer of funds.
- Reporting: Provides detailed transaction reports for analysis and reconciliation.
How Payment Gateways Work
The process of using a payment gateway generally involves several key steps:
1. Customer Order: A customer enters their payment details on a merchant's website.
2. Encryption: The payment information is encrypted and transmitted to the payment gateway.
3. Authorization Request: The payment gateway requests authorization from the issuing bank.
4. Approval/Denial: The bank approves or denies the transaction.
5. Processing: The payment gateway processes the transaction and redirects the customer to a confirmation page.
