Abstract
A method and apparatus are provided for reducing power consumption in a data collection device. The method includes providing a power detector in an interface component of the data collection device and sensing the power delivered to the scan engine component of the device using the power detector. The power delivered to at least a portion of the interface component is selectively reduced according to the sensed power delivered to the scan engine component.
