DIRAK Inc. has developed a hands-free system to automatically control access to cabinets outfitted with the company's E -Line handles. This new Wireless Active Key continuously transmits signals to nearby E-Line handles, whose on-board electronics then determine whether to grant or deny access. Keys can also monitor employee location, turn lights on or off, and control room access. Visit www.dirak.com for more info.
