Frequently asked questions

What is the difference between a payment gateway and a payment processor?

A payment gateway captures and transmits payment information from the customer to the processor, while the payment processor executes the actual transaction by communicating with the issuing and acquiring banks.

What is interchange-plus pricing?

Interchange-plus pricing passes the exact wholesale interchange fee charged by card networks directly to the merchant, adding a transparent, fixed markup fee for the processor.

Are payment processors compliant with PCI DSS regulations?

Yes, reputable payment processors are certified as compliant with Payment Card Industry Data Security Standards to ensure secure handling of cardholder data.
