Sometimes we lose money. Maybe will lose the cards. People steal money. Maybe someone will take the card. Someone may even make a card that looks like our card. Since we can’t buy anything without our cards, the credit card may be no better than currency.Is there something even easier to use than credit cards？ All of us have a thumbprint. No two thumbprints are the same. Maybe someday the government will keep people’s thumbprints with a number. No person will have the same thumbprint or number. When you want to buy something you will put your t thumb on a machine or a computer. Each store or business will have one. Everyone’s thumbprint will be in the computers. It will be very difficult to lose our thumbprint. It will be difficult for someone to steal it or to make one like it.
