UPS delivering updated handheld for drivers - Atlanta Journal Constitution The handheld device that UPS drivers use as the primary tool of their trade is getting smaller and smarter. It could soon be as small as a fancy remote control. UPS and Honeywell International announced Wednesday they are creating a new device called the DIAD V, or Delivery Information Acquisition Device, fifth-generation. Brown-clad UPS drivers use the DIADs to scan packages on pick-up, track them during transit and confirm delivery. The devices also have route maps and can send messages to redirect drivers. FedEx drivers use a similar device.
