Techniques are generally described that relate to a computer-implemented method of using a virtual device operating in a first computer network to perform a service on behalf of a low-power device operating in a second computer network includes receiving, by the virtual device, device data reports and a device descriptor from the low-power device. A connecting conductor is joined to the cap, and a plunger conductor assembly is electrically connected to the connecting conductor. The invention allows a user to create, edit, and store profile information including secure data and corresponding biometric identifiers. Additional information on the selected activity field is then presented using the client user interface.
