1. The purpose of the code reader:

Industrial barcode readers are installed on the production line to read the barcodes on the products transmitted by the assembly line.

Due to uncertain factors such as barcode printing clarity and factory scanning environment, it is necessary to be able to fix the installation, scan the product barcode at multiple angles, and quickly read the product barcode of the conveyor belt in batches, so the barcode scanner must have a high-sensitivity recognition ability, support automatic scanning and command control and other working modes, and avoid the unstable scanning of the barcode scanner.

2. The working principle of the code reader:

The main principle is to use the software that comes with the device to identify the characters of the one-dimensional code two-dimensional code, and the one-dimensional code/two-dimensional code is arranged according to certain coding rules to express a set of information graphic identifiers. It is mainly used for product tracking, production control, automatic identification, especially with the current emerging RFD technology, which constitutes one of the hardware systems of the "Internet of Things".
