Vending machines have started accepting credit cards instead of cash. A study by USA technologies has discovered that when vending machines accept credit cards then spending goes up 76%. Since credit cards are becoming the dominant payment choice, then in the future all vending machines will probably accept major credit cards. How many times have you tried to force a crumpled dollar into a vending machine? How much easier will it be to just insert your credit card? The reason that spending has increased so much is that when customers use credit cards they don’t really feel like they are spending real money. Are you one of those people? Are you spending money you don’t have? If you are, then try leaving the credit cards at home, and paying for your expenses in cash.
