Tool Link: RFID tells you if you've left anything behind

DVICE: "Always losing stuff? If you carry an assortment of expensive gear around, here's a great idea that will assure you you'll never again leave anything behind. DeWalt teamed up with Ford Trucks to create Tool Link, a radio-frequency identification (RFID) tag reader that electronically accounts for each item on which you place a small transmitting tag. Using two RFID antennas in the truck bed, when you press a button on the in-dash computer screen it does an electronic roll call, showing you if any of those valuable tools are missing."
