"The next time you use the office printer, you may be printing up a lot more than sales figures or quarterly reports. Many color laser printers are secretly embedding tracking dots, minute and almost invisible yellow specks, on documents. While many have speculated on the meaning of the dots, the Electronic Frontier Foundation (EFF) appears to have decrypted the code."


Simple idea... very useful for tracking...
