A system for detecting placement or misplacement of an object includes a wireless tag; a first electronic device (“FED”) associated with the tag to automatically detect signals from the tag, determine a position of the FED, transmit the position and status to an external electronic device or network (“EED”) in response to the status indicating that the tag and the FED are within a predetermined range, and transmit the position and status to the EED in response to the status indicating that the tag and the FED are outside of the predetermined range; and a second electronic device (“SED”) that is unassociated with the tag to automatically detect signals from the tag, determine a position of the SED, determine an identifier for the tag using the signals, and transmit the position of the SED and the identifier to the EED.

An identification badge system has 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 base station has at least one docking receptacle for docking the badge. The badge has a housing and an e-paper display. The housing docks for communicating the electronic image from the base station to the e-paper display and/or for charging. The e-paper display maintains the electronic image when the badge is removed from the receptacle. The base station erases the electronic image from the e-paper display when the badge is re-docked. The badge has an RFID tag for communication with standard access control readers, writers and controllers and has a Wi-Fi transponder and associated circuitry for tracking visitor locations by sending a RF signal to Wi-Fi routers or Bluetooth beacons. Visitor location can also be ascertained using GPS.

A system for detecting placement or misplacement of an object, comprising: a wireless tag; a first set of instructions which cause a first electronic device (FED) associated with the tag to automatically detect signals from the tag, determine a position of the FED, transmit the position and status to an external electronic device (EED) in response to the status indicating that the tag and the FED are within a predetermined range, and transmit the position and status to the EED in response to the status indicating that the tag and the FED are outside of the predetermined range; a second set of instructions which cause a second electronic device (SED) that is unassociated with the tag to automatically detect signals from the tag, determine a position of the SED, determine an identifier for the tag using the signals, and transmit the position and the identifier to the EED.

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.
