In the future, l don't think people will use cash, checks, or even credit cards. Instead we'll just use our fingerprints. When we are born, We will get a bank account. We will have the same account for our 5 whole life, and it will be connected to our fingerprints Everyone will have fingerprint recognition devices. So instead of scanning credit cards, we'll scan fingers. Life will be so much easier when we don't have to carry around money or credit cards! Jason, Alaska
