I'm hunting for a library book that I need to return. where did I put it? (and can technology help me find it?)
All of the library books I have are tagged with RFID chips, which is used for inventory control. That should mean that I can use something like this 3M RFID locator device as a reader and scanner to locate a lost item.
(And, at that point, I'm almost ready to put a chip in my glasses to help locate them.)
