Payment Gateway
The service that securely processes a shopper's card details and authorizes a transaction between checkout and the bank.
In practice
It encrypts and transmits card details between the checkout page and the payment processor, then returns an approval or decline almost instantly - most businesses use a third-party gateway rather than building this infrastructure themselves, given the security requirements involved.
A shopper enters their card number at checkout; the payment gateway securely passes it to the card network for approval before the order is confirmed.
Why it matters
A slow or unreliable payment gateway directly costs sales at the final, most critical step of checkout - a failed or laggy transaction there is one of the most expensive possible points of friction.
Worth knowing
- Encrypts and transmits card data without the merchant directly handling raw numbers in most setups.
- Response time and uptime reliability matter as much as the fee structure when choosing one.
- Supporting multiple payment methods through one gateway simplifies checkout integration.
