This extension allows you to use NAB Transact as a credit card processor. You can process Visa and Mastercard by default, and optionally accept American Express, UnionPay (UPOP), Diners Club and JCB after activation from NAB. The gateway also supports Subscriptions, refunds, risk management and pre-authorization.
As of version 2.0, this gateway supports both Direct Post and XML API integration methods offered by NAB Transact.
Using the Direct Post method, after checkout your customers will be directed to an additional page on your website (with all of your branding/header etc) which accepts their credit card details. These details are sent directly to NAB servers, bypassing your server and the need to worry about PCI-DSS compliance. If the user chooses to pay with UnionPay (UPOP), they will be redirected to an additional external page to complete payment.
