Our History

After looking for an omnichannel payment gateway that would meet the needs of its merchant base, our parent company, Fidelity Payment Services, discovered there just wasn’t one on the market that offered the level of flexibility desired. So, Fidelity decided to build its own gateway. And with that, Cardknox was born—a payment gateway loaded with features and ready to be integrated with a wide variety of payment hardware, software, and e-commerce platforms.
