The shipping giant, which calls itself “Brown” in its advertising, is beginning to deploy a tracking system that combines the Wi-Fi and Bluetooth wireless technologies. Bluetooth can carry data over several feet, while Wi-Fi has a 300-foot range, making it a popular method of extending Net access in many homes and business.
UPS representative Ginnie Myhr said 55,000 package handlers eventually will get Bluetooth bar code readers that are worn on the finger like a ring. The ring scans a package label and sends the information to a Wi-Fi radio attached to a handler’s belt. The radio then sends the information to a central computer.
