Connect To The Card Brand Networks

Payment gateways are online systems or interfaces that provide real-time authorization of credit cards when a customer places a card-not-present sale, order, or transaction. The gateway typically has two components: 1) a Virtual Terminal, which turns your existing computer into a functioning payment terminal by allowing you to securely log in and key in credit card numbers, and 2) an API, or Application Programming Interface, which enables merchant shopping carts or other software to connect to the gateway to allow for real-time processing.

All National payment gateway options provide automatic screening of sales orders for fraud in real time prior to the authorization request being sent to the National platform. Fraud detection tools are available which include geolocation, velocity pattern analysis, delivery address verification, computer finger printing technology, identity morphing detection, and basic AVS checks.
