Two rather clever gentlemen from the Netherlands have created a new system of tagging and tracking books, DVDs, or various other media that will undoubtedly find its way into libraries and businesses in no time at all. The program works by utilizing small RFID tags placed inside of books, and an array of sensors attached to the shelves. The data concerning an item's movement on or off the shelf, as well as the its position when not in use is then communicated to a terminal, providing the means of locating not just whether a piece of media is available, but its exact physical location. No word on when or how this will be made available, but for those of us with large book collections, we wait with bated breath. Check the demonstration video after the break.
