METHOD AND APPARATUS FOR ALIGNING A CODE AND A READER WITHOUT DISPLAYING A BACKGROUND IMAGE

摘要

A method and system for verifying a two dimensional mark without the need to transfer an image between a verification system having a data collector and host software connected to a display, the method comprising the steps of displaying a blank background image corresponding to the data collector field of view on the display, using the data collector to scan for a code at least in part within the field of view, identifying an item that may correspond to a code, graphically representing the identified item on the display in a location corresponding to the actual location within the field of view, monitoring the position of the identified item, attempting to verify the code when the identified item is at an aligned position, and indicating that the code has been verified. In one embodiment, an image of the code only may be displayed and/or transferred to the host software.
