Network Merchants (NMI) Payment Gateway For OpenCart
[box type="info"] Guaranteed to work on the latest version of OpenCart[/box]
This plugin extends the functionality of OpenCart to accept payments from credit/debit cards using the Network Merchants (NMI) payment gateway. This plugin enables you to use the Network Merchants (NMI) payment gateway to accept credit cards directly on your OpenCart website without redirecting customers.
Simply upload the contents of the purchased .zip file to your OpenCart directory. Once the files are in place, all you have to do is 'Install' the extension from the OpenCart extensions page. After installing, you will have only a few fields to fill out before you are ready to accept credit cards on your store.
This payment gateway allows you to accept credit cards directly on your website and therefor to remain PCI Compliant you must protect the checkout page with SSL. However, the plugin will function with or without SSL on.
