Realex Direct Payment Gateway

Realex Direct

Realex Redirect for WordPress is a gateway plugin that allows you to safely and easily accept credit card payments with Realex, without the need for an SSL certificate or undergoing costly PCI compliance.

Customers are automatically redirected to Realex’s secure servers for payment with their hosted payment form, meaning that their credit card information never touches your servers and you don’t need to spend time installing and managing SSL certificates, and can focus on selling more goods and services. With Realex you can accept payments from Visa, MasterCard, American Express, Laser, Switch and Diners Card.

For a more seamless and integrated checkout process where the customer never leaves your site, consider the Realex Realauth Remote Payment Gateway however you will need to pay for an SSL certificate each year for this type of gateway.
