Staying Compliant with Surcharging Rules

Surcharging—the practice of adding a fee to a transaction when a customer pays with a credit card—is a powerful tool for offsetting processing costs. However, it is governed by a strict set of rules enforced by the card networks (Visa, Mastercard) and varying state laws.

Implementing a surcharge program incorrectly can result in severe fines and the potential loss of your merchant account. It is critical to understand the boundaries of this practice.

Crucial Surcharging Regulations

• Credit Cards Only: By law, you cannot apply a surcharge to debit cards or prepaid cards, even if they are run as "credit" at the terminal.
• Cap Limits: Surcharges cannot exceed your actual cost of processing, and the card networks strictly cap the maximum surcharge amount (currently around 3%).
• Clear Disclosure: You must clearly notify customers of the surcharge at the store entrance and at the point of sale, and the fee must be listed as a separate line item on the receipt.

CorePro360's smart terminals are pre-programmed to handle these compliance requirements automatically, instantly identifying card types and applying the correct, legal fees without manual intervention.

Frequently Asked Questions (FAQ)

Is surcharging legal in my state?

Surcharging is legal in most states, but a few still have restrictions or bans. Always verify your local laws before implementing a program.

How is surcharging different from dual pricing?

Surcharging adds a fee at the register for using a credit card. Dual pricing displays both a cash price and a card price upfront, letting the customer choose.

Do I need special hardware to surcharge?

Yes, your POS system must be capable of automatically identifying credit vs. debit cards and applying the surcharge only to eligible transactions.
