The rules

  • 2 The merchant must inform their customers of the credit card fee with appropriate signage at the store entrance (if applicable) and at the point of sale.

  • 4 The credit card fee and the price of the product or service must be processed together as one transaction.

Advocacy

CardX by Stax is not just a payments company, but a recognized authority and a strong advocate for merchant affordability and consumer fairness.

We were the only solution provider to file a brief in Expressions Hair Design v. Schneiderman, contributing real-world expertise to a landmark U.S. Supreme Court case.

In March 2017, the Supreme Court held that state “no-surcharge” laws restrict constitutionally protected speech.

Social impact

This victory was celebrated by the merchants and their amici, including not only businesses such as Spirit Airlines, Kroger, Walgreens, and CardX, but also policy experts and think-tanks advocating for solutions that lower transaction costs, especially for low-income or under-banked Americans, who more often pay with cash and debit.

This cause has united supporters across political lines, who emphasize that passing on the credit card fee is the best tool a merchant has for informing the customer of the transaction cost and giving the customer the incentive to reduce it.

Increase your margins without the hassle

Businesses incur billions in interchange fees each year. With CardX by Stax, they don’t have to.
