Someday in the future we may not need to have money in our pockets. Is life easier whe

n people don’t need to carry any coins for currency at all？ Is money heavy to carry？ Is it safe to carry money？ Maybe in the future each of us will have only one small plastic credit card. We will use it to buy all the things we now buy with money. We will not need money to pay for things.Of course we may still have some of the same problems with cards that we now have with money. 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.
