Core Viewpoint - A recent settlement between Visa and Mastercard and U.S. merchants may allow merchants to charge different fees based on the brand and tier of credit cards used, following a long-standing legal dispute over interchange fees [1][2]. Group 1: Settlement Details - The settlement arises from a two-decade legal battle regarding interchange fees, which are fees banks charge merchants for credit card transactions [2]. - Merchants would gain the ability to impose varying fees for different tiers of credit cards under the new agreement [2]. Group 2: Impact on Merchants - The "honor all cards" rule, which mandates that merchants accepting Visa or Mastercard must accept all versions of those cards, is a focal point of the settlement [3]. - Merchants could potentially "discriminate" against higher-tier cards that incur higher processing costs, such as the Visa Infinite card, which can cost 15 basis points (0.15%) more to accept than a mid-tier Visa Signature card [4][5]. Group 3: Consumer Implications - If merchants opt not to accept higher-tier cards due to increased costs, they risk losing customers who prefer to earn rewards on their purchases [5]. - The settlement requires that different classes of credit cards have "clear visual markers" for identification by both merchants and consumers, although implementing these changes may take years [6].
