Hitachi today announced AirLocation II Tag-w. This RFID-enabled device is a simple way for employers to keep tabs on their employees while they’re at work, hopefully working. When you get to the office in the morning, you’ll walk through the door with its sensor which will activate you for the day. Then the guys in charge will know where you are all day (assuming you have the nametag on). Hitachi is pitching this mostly for emergency situations. If the building collapses while you’re in it, the EMTs will be able to find you—if you had your nametag on.
