Abstract
A laser bar code is provided with a check sum that serves to validate the read accuracy with the action of reading itself. A bar code reader system includes a frame grabber in conjunction with video image processing software that utilizes the check sum to ensure accurate reading. The reader is used to check the accuracy and readability of the bar code mark and also for downstream bar bode reading.
