    A scanner is a machine that reads bar code information. Using the infrared light source, and then according to the results of the reflection, the use of chips to decode, and finally return to the bar code represented by the correct characters. Is a machine that reads bar code information. Using the infrared light source, and then according to the results of the reflection, the use of chips to decode, and finally return to the bar code represented by the correct characters. The bar code is made up of black and white lines, and the bar code scanner determines the width of the bar code by the difference in the degree of infrared reflection between black and white.

    Bar code scanner with sensors, according to the reflected light intensity of different high and low voltage generated, resulting in logic data, the general cable scanning guns are mostly plug and play, only need a data cable to connect to The computer can be used immediately, do not need other operations. The wireless bar code scanning gun will generally have a standard base, and this base is from the transmission of data and the role of charging, so before the start of scanning, scanning the network to be wireless scanning gun and base matching, You can start scanning, after scanning the bar code, we also need to scan the bar code through the base to the computer and other terminals.Barcode Scanner

    Supermarket scanner is actually a bar code into a number of converters. This device is basically divided into two types, scanning guns and scanning platforms. Their role is very simple, the bar code graphics through infrared detection into digital signals. For the cash register equipment or background management equipment call. The cash register with the POS machine is the scanning gun, it does not store the function, it will scan the data spread to the computer storage, inventory with the disk or data collection device, which itself is a computer, the principle and the same phone, There are CPU, memory, FLASH, you can also insert the memory card, in the end where there is a program, as the computer to open a web page or program, you can upload data directly to the server, you can also exist in the computer (collector) , And then need to upload to the PC or server. This depends on how the program is written.Barcode Scanner
