Do you use a color printer? PC World magazine reports that every color printer in the world has a tracking code that can be seen with special equipment when necessary. Every sheet that is printed with this code via a program and the identifiers can tie the printer directly back to you. The purpose is to shut down counterfeit money makers, who have grown out of control in the world. The government has gone to extreme measures to counteract counterfeiters with new designs of bills and holograms on money. But crooks have been able to duplicate them. So what percent of counterfeit dollars are coming from a printer? About 60 percent, according to the Secret Service. So, just be aware that your printer is spying on you.
