We can model this: Divide a quantity of fluid inside a vial that contains a number of microchips into six equal parts, for drawing up into a syringe, at random. What is the chance that you’d end up with at least one chip in each draw? If you had just six microchips in there, it would be less than 2 percent. Double that to 12 microchips per vial, and the chance of success is about 45 percent. In order to be 95 percent sure that each syringe contains at least one government-certified tracking device, do you know how many chips would need to be in the vial? Twenty-six. That would be astonishingly inefficient. And worse: If these are supposed to be unique personal identifiers, imagine the chaos of a system in which one person might carry several microchips while other, uh, “sheeple” have just one.
