The #1 name in zero-cost.

CardX by Stax passes on the credit card fee and enables the customer to choose a lower-cost option, making payments more fair for everyone.

Our Story

Innovation at the intersection of technology and compliance.

New Rules

In 2013, new rules enabled businesses in America to do what universities and government had long been permitted to do: pass on the fee when customers choose credit cards for convenience or rewards.

We founded CardX because we recognized the opportunity to provide much-needed relief.

For American businesses, credit card acceptance is one of the largest, and fastest-growing, operating costs.1 In fact, since 2005, the interchange cost of Visa’s and MasterCard’s premium rewards cards has risen by 24%.2

And yet, while these costs were increasing in America, they were decreasing throughout the rest of the world. In countries where passing on the credit card fee is permitted, economic research shows that the cost of card acceptance has been significantly reduced.3

New Solution

By passing on the credit card fee and enabling the customer to choose a lower-cost payment option, CardX creates cost transparency and equips customers to “comparison shop” among payment types. This applies competitive pressure to the prices charged by credit card companies.

As a turnkey solution provider powered by patent-pending technology, we differentiate ourselves at the leading edge of technology and compliance. The CardX solution is designed for seamless compliance in the evolving regulatory landscape—and we’re the ones leading the change, all the way to the U.S. Supreme Court.

The #1 name in this growing field, we license our solution to industry-leading software companies and merchant services providers. Every day, CardX and our partners bring zero-cost credit card acceptance to government entities, schools, and businesses of all sizes, from Main Street merchants to public companies.

In November 2021, CardX was acquired by Stax Payments, the all-in-one payment technology provider. As one of Stax’s key product offerings, CardX + Stax are empowering more businesses than ever before to implement surcharging across the United States and, as of 2022, as the first surcharging solution available in Canada.
