By one estimate at least 15% of all drugs sold are counterfeit resulting in thousands of deaths. One reason Vardex Laser developed a technique to etch individual pills with 2-D bar codes in a process that takes “less than a millionth of a second” to mark a product in a process that is completely “clean and safe.” The codes can be read by an optical scanner or even seen with the naked eye, and are said to be “nearly impossible” to counterfeit. Unless you have a laser cutter, that is.
