Abstract: An identification badge system having an image relaying device for communicating an electronic image, a base station for communicating with the image relaying device, a readiness indicator, and a reusable badge. The badge has a housing, a colored e-paper display, a radio frequency identification tag, and a Wi-Fi transponder and related circuitry that sends radio frequency signals to Wi-Fi routers or Bluetooth beacons in the facility using the system for real-time location tracking of the badge using GPS. Backscatter can be used to encode information on the Wi-Fi signals with little or no battery energy. Tracking information can be stored apart from the badge. The base station has at least one docking receptacle for docking the badge for charging only or also for communication of the electronic image to the badge e-paper display and for erasing the image from the display.
