New payment network rules that allow retailers to assess “check out” fees or surcharges on credit card purchases took effect in many states on January 27, 2013. Visa and MasterCard rules previously prohibited merchants from charging surcharges on credit card purchases. The charges can be up to 4% and are imposed at the merchant level on credit card transactions. Debit cards are not impacted and there are no surcharges at the issuer level. Merchants intending to surcharge must provide clear disclosures of surcharging practices to consumers at point-of-entry and point-of sale and include a line item on the receipt with the actual surcharge amount.
