Credit Cards
Credit cards were invented by a man named Frank McNamara. He realized the problem that paying cash on the spot caused. People might not be able to pay cash on the spot because they might have forgotten it of they might not have any money on them at the moment. He reaized this when he was out for dinner and he forgot that he didnt bring any money.
