Counterfeit money

Counterfeit money is fake money that looks like real money. People who make counterfeit money use printers or computers to print or copy money, or try to make it look like the real thing. Usually, it doesn't have the same special marks and designs that real money does. That's why police and people at the bank, like tellers, can spot it easier. If someone tries to give you counterfeit money, don't accept it because it's illegal to have and use.
