Low frequency

Low frequency: From the “no way this will ever happen” department, here’s an article regarding printers’ ink that can be “tagged” in such a way as to issue some type of radio frequency. While the primary application is in packaging and inventory tracking, I think there is no way the fantasy scenario suggested in the story will ever play out. I can’t imagine how one can balance the ability to “track” where a newspaper or magazine is “passed along” with the outrage such privacy-threatening technology will raise from, well, anyone with half a brain.
