This extension allows you to use NAB Transact (direct post mechanism) as a credit card processor. You can process Visa and Mastercard by default, and optionally accept American Express, Diners Club and JCB after activation from NAB. Credit card details are sent directly from your checkout page to NAB servers, where they are processed and the user is redirected to your Thank You page. As the credit card details never touch your server, there's no need to worry with complex PCI compliance (Payment Card Industry Data Security Standards) while delivering a seamless customer experience.
