  • "After using PcCharge software for many years to process our credit card transactions, it was necessary to move to a more secure system. After evaluating numerous solutions, we are glad that we chose Cardknox. Cardknox provides a fast, cost effective, secure credit card processing solution that includes tokenization. Transitioning to the Cardknox system was a smooth process thanks to the responsive technical and customer service support staff."
