Introduction
The GM73 code reader module is a high-performance code scanner that can capture common 1D and 2D codes like Barcode and QR on labels, papers, or even screens at a high speed of about 1s.
The module comes with superior reading performance utilizing advanced decoding algorithms based on smart image recognition, which is able to read all kinds of codes accurately. The scanner allows users to configure parameters by scanning setup codes, greatly reducing development difficulty. Besides, it has onboard micro USB and UART and can be conveniently embedded into various devices like self-service vending machines, metro gates, access control, checkout counter, and so on.
