1 Introduction of Module
1.1 Introduction
GM72 Bar code reader module is a high performance scanner, can read 1D
bar code easily and read 2D bar code with high speed. It also wins high scan
speed for linear code, even for bar code on paper or screen.
GM72 bar code reader module is an advanced bar code decoding
algorithm which developed on image recognition algorithm, can easily and
accurately read bar code, simplify secondary development.
