Abstract: An UV sterilization device includes a housing defining a cavity, a tray carried within the cavity and configured to receive a device, the device including an RFID tag, and an NFC device configured to communicate with the device when external to the cavity and unlock a door when the device is authorized, and a UV CBA carried within the cavity adjacent the tray and having LED UV sources configured to irradiate the device with UV radiation. The UV sterilization device also may include an RF transmitter configured to energize the RFID tag, and a controller coupled to the RF transmitter. The controller may be configured to determine a position and a number of the device based upon the RF signal from the RFID tag, and selectively power the UV CBA for disinfecting the device based upon the identification of the device.

Abstract: A method is for operating a UV sterilization device including a housing defining a cavity, and having a door configured to permit access to the cavity, and trays carried within the cavity. Each tray is configured to receive a mobile wireless communications device. The UV sterilization device may include UV CBAs carried within the cavity respectively adjacent the trays, each UV CBA having LED UV sources configured to irradiate the mobile wireless communications device with UV radiation. The UV sterilization device may include a controller, and the method may include operating the controller to selectively power one of the UV CBAs for disinfecting the mobile wireless communications device.
