Debit Cards

When customers choose a credit card, they also cover the fee.

At the time of purchase, CardX informs the customer of the fee amount, and always gives the option to pay with a no-fee method. You receive 100% of the amount of your sale.

When customers choose a debit card, they pay no fee, keeping you compliant.

Your customers always have a no-fee payment option. To comply with the rules, CardX automatically detects when a debit card is entered and applies no fee. You pay only the low cost of debit card acceptance.

CardX by Stax Serves Leading Companies:
We’re the #1 name in zero-cost transactions.

Before we learned about CardX, we were reluctant to accept cards due to the high cost. With CardX, customers simply use a credit card and I get the full sale amount deposited to my account the next day.

CardX really takes all the complexity out of accepting cards.

They even ship us more paper for receipts at no cost whenever we ask! Everything has worked so well that we're starting to use the solution at a second location this month.”

The Problem

Unless businesses pass on the credit card fee, they have to either raise prices across the board—harming customers who pay with cash or debit—or accept a lower profit margin on credit card sales.

Our Solution

CardX allows customers to pay the fee if they choose a credit card for convenience or rewards, or to use a low-cost debit card with no additional fee.


CardX serves businesses in 48 states plus the District of Columbia.
CardX does not yet serve businesses in CT and MA.
CardX is available in Maine and New York, and additional terms apply.
