Credit card payment networks like Visa, Mastercard, American Express and Discover permit participating merchants to impose credit card surcharges, when allowed by law. However, they place multiple restrictions on this practice.
Understandably, Visa, for example, officially opposes surcharging as a practice, because it penalizes cardholders from using their preferred method of payment. Merchants that choose to impose surcharges are required to notify Visa at least 30 days in advance of implementing the policy.
Furthermore, merchants are required to create signage at the point of entry and point of sale, alerting customers about credit card surcharges, and they must itemize the surcharge on transactions. Finally, the surcharge must not exceed the merchant’s cost of accepting the credit card. American Express, Mastercard and Discover all have similar requirements for merchants that choose to impose surcharges on their customers.
