counterfeit money

Laser-printing technology makes it extremely easy to counterfeit money and documents, and the dots, according to supporters, in use in some printers for decades, allow law enforcement agencies to identify and track down counterfeiters.
However, the same dots could also be employed to track a document back to any person or business that printed it. Although the technology has been present for a long time, printer companies have not been required to notify customers of the feature.
If this practice disturbs you, don't bother trying to disable the encoding mechanism of your printer—you'll probably break it. The coding device is a chip located deep into the machine, near the laser. It embeds the dots when the document is about 20 billionths of a second from printing.
Although nobody has an estimate of how many laser printers, copiers, and multifunction devices track documents, experts believe that the practice is commonplace among major printer companies. The U.S. Secret Service would agree that it finds the printing industry quite helpful to law enforcement.
According to sources, counterfeiting cases are brought to the Secret Service, which checks the documents, determines the brand and serial number of the printer, and contacts the company. Some, like Xerox, have a customer database, which they share with the government.
Many people are apprehensive that the American government’s tracking initiative could lead to a serious breach of privacy. The government has already succeeded in persuading more colour laser printer manufacturers to encode each page with identifying information. Without your knowledge or permission, an act you assume is private could become public. A communication tool you use in everyday life could become a tool for government surveillance. And what's worse, there are no laws to prevent its abuse.
