Cardknox is an omni-channel payment processing gateway that provides customized payment solutions to thousands of merchants in all major retail verticals. The gateway supports a wide variety of processors and platforms, and utilizes proprietary Intelligent Routing technology to ensure smooth and uninterrupted transaction processing.

The Cardknox payment gateway extension for Magento 2 makes it easy for store owners to start accepting a variety of payment methods while continuing to take full advantage of Magento software. In addition to benefiting from frictionless payment processing, merchants who integrate with the Cardknox gateway will have access to tokenization technology to keep transactions out-of-scope and simplify PCI compliance.
