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.
