Now is an era of high technology, but also an era of pursuit of speed. In order to pursue speed, many companies have gradually used machines or high-tech products to replace manual work. Barcode scanner is one of them. Barcode scanners are generally used for data collection. Compared with manually inputting and collecting data, barcode scanners are not only much faster, but also less prone to errors.

Nowadays, barcode scanners are used in many fields, and there are also many scanners with different performance models. Generally, scanners with different performances are used for different usage environments and scanning applications. For example, store cashiers generally only need to use relatively ordinary performance, and some electronic industries generally use very good industrial-grade scanners when reading the laser engraving codes of electronic parts, because many electronic parts are very small. At the same time, the laser-engraved code has low contrast, and the shape of some electronic parts is very irregular, and the barcode above is not on the same plane, and reading is very difficult. So choose an industrial-grade scanner.
