ABSTRACT:
A method, system, and computer program product for implementing presence detection is provided. The method includes a first mode of a tri-modal application that monitors a field-of-view via a presence detection function of a scanner. The method also includes implementing a second mode of the tri-modal application when a change to the field-of-view is detected and a specified threshold of change is met. The second mode includes activating selected system components of a terminal device, which in turn include a processor and the presence detection function. The second mode also includes fully activating the scanner and monitoring the field-of-view for determining a bar code image. The method further includes initiating a third mode of the tri-modal application when the bar code image is detected at the scanner. The third mode includes activating an illumination component of the scanner, reading the bar code image, and deactivating the illumination component when the bar code image has been read before returning to the second mode.
