Heads up, points chasers: Visa and Mastercard just proposed a deal that could let stores pick and choose which of their cards they accept. Translation: your fancy rewards card might get the cold shoulder at checkout, or you could see extra fees for using it. Merchants are tired of paying higher fees for premium cards, so you might need a backup card (or two) in your wallet just in case. Time to double-check your payment options! #Business #MakeMoney #CreditCards
