Description
GM803 serial have GM803-S and GM803-L model.
The only difference between GM803-S and GM803-L is the lens.
GM803-S lens reading distance is 5-30cm.
GM803-L lens reading distance is 7-50cm.
(The actual data depends on the size and content of the code)
GM803 serial 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.
GM803 serial 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.

QR code technology: a new chapter in manufacturing
Today, scanning modules are no longer a novelty, but their importance cannot be ignored. It has been deeply integrated into our daily lives and has become a key tool for improving efficiency in all sectors. The carrier of this amazing technology is the scanning module.
The nature and operation mechanism of scanning module.
Scanning module is a kind of precision optical equipment, it through the light source, optical system and light-sensitive components of the precise cooperation, quickly capture the image information of the target object, and accurately convert it into digital signals. It is capable of handling diverse images and is widely used in many fields such as barcode identification and industrial inspection.
In the face of problems such as blurred images, colour deviations or recognition difficulties, the scanning module can optimise image quality by adjusting parameters such as resolution, brightness or colour balance. At the same time, for data transmission interruptions due to loose or damaged cables, the data flow can be restored by simply checking all connections or replacing damaged parts.
Scanning modules are widely used in a variety of fields. In the area of document processing, scanning modules can help convert paper documents into electronic documents, significantly improving the efficiency of document storage, management and retrieval. In the field of image processing, it can convert various images into digital signals for subsequent editing, processing and transmission to provide convenience.
The development potential and application prospects of scanning modules are extremely broad. Whether it is daily life, industrial production, or
security monitoring and other fields, scanning modules play a pivotal role. In the future, with the continuous progress and innovation of technology, scanning modules will show its unique value in more areas, bringing more convenience and safety.
