A hand-held wireless communications device includes a camera integrated within a housing of the wireless communications device, a front-facing lens assembly to focus light onto the camera, a display, and a controller connected to the camera and the display. The controller controls the camera to capture an image of another device that is in front of its display. The device can then analyze the image to extract information specific to the other device, and utilize that information to identify and authenticate the other device. Once identified and authenticates, the devices are able to share data and information with each other.
