We allow merchants to accept payments through all channels – in-store, online, via mobile payments, and in unsupervised locations, such as fuel pumps. Whether you can use an inter-channel channel or more, we can help you speed up the checkout, deliver innovative customer experiences, and deliver loyalty and rewards. Nothing in Mastercard`s rules affects a trader`s obligation to comply with existing state or federal laws, including, but not limited, state laws that may prohibit or limit the burden of credit transactions, and federal and regional laws regarding misleading or misleading claims. As a mastercard processor or dealer, you are essential to our success. And this success is best guaranteed if you have access to mastercard rules and if you understand them, and how they can apply to your business. The ability of a trader to impose a market depends on the merchant`s satisfaction with certain advertising obligations. These advertising obligations include prior notification to mastercard and the merchant`s purchaser of the merchant`s intention to apply a surcharge, no less than thirty days before the merchant pays a surcharge. A merchant can fulfill his obligation to disclose to Mastercard by clicking here and providing the following information: The amount of the fee that a merchant can charge a cardholder is limited in relation to the cost of the merchant accepting Mastercard credit. For merchants who opt for a brand supplement, a merchant may only count a Mastercard holder at a price below the average effective discount of the merchant that the merchant pays to the purchaser for the purchaser`s mastercard or the maximum allocation limit found below. For merchants who charge a product supplement, the surcharge cannot be higher than the cost borne by the distributor for the acceptance of the Mastercard credit product, net of the ceiling of the durbin modification for debit interchange commissions. Merchants can apply either a branded supplement or a product surcharge on Mastercard credit cards. A brand supplement is a brand-level surcharge, in which the merchant calculates the same percentage on all Mastercard credit cards.
