Fake money refers to counterfeit currency that is produced without legal authorization. It is designed to look like real money, such as U.S. dollars or euros, but is not issued by a government or central bank. Counterfeiting is illegal and can lead to severe penalties for those caught producing or distributing it. The production of fake money often involves sophisticated printing techniques and materials to mimic the appearance of genuine currency. Governments and financial institutions employ various security features, like watermarks and holograms, to help people identify authentic bills and prevent the circulation of counterfeit money.
