Abstract: A multi-device alert notification system that includes a trigger device that has a low energy wireless transmitter for broadcasting an alert message in unlicensed spectrum for mobile user devices when activated, and a remote server system storing information that identifies the trigger device, the remote server being configured to receive, through a network, an alert notification message from each of a plurality of mobile user devices, each alert notification message indicating that the mobile user device has received the alert message from the trigger device and including a unique trigger device identifier and a unique user identifier associated with the mobile user device.

Abstract: A radio frequency identification (RFID) device is described. In one implementation, there is provided a keyboard emulator; a first keyboard interface configured to receive an operative connection to a host computer, and operatively connected to the keyboard emulator; and a controller configured to receive data from at least one RFID tag; and transfer the data through the keyboard emulator and then the first keyboard interface in response to a user-initiated route instruction received by the controller, wherein the keyboard emulator converts the data to corresponding keystroke codes.
