Visa and Mastercard are nearing a settlement with merchants to end a 20-year-old dispute over credit card fees. The agreement aims to lower fees, which currently range between 2% and 2.5%, by an average of 0.1 percentage point over several years. Under the terms being discussed, merchants will have more power to reject certain credit cards, with rules requiring acceptance of all network credit cards loosened.
