The Working Principle Of Barcode Scanner

- Jun 12, 2017 -

  The scanner is a machine that reads barcode information. Using the emitting infrared light source, and then based on the results of reflection, using the chip to decode, and finally returned to the bar code to represent the correct character.

  Bar code is a combination of black and white lines, and bar code scanner is the use of black and white to the infrared reflectance to determine the width of the bar code. There are sensors in the barcode scanner that generate different voltages depending on the intensity of the reflected light, which in turn generates logical data.Barcode Scanner

  If you purchase a scanner, there should be a matching software, of course, there are matching database software (pay to buy). The first thing to do is to record the corresponding item to the database and assign it a barcode, which is the basic work. Various types of scanners function different, and some can directly print barcode.Barcode Scanner

There are sensors in the barcode scanner that generate different voltages depending on the intensity of the reflected light, which in turn generates logical data.

  The logic signal received by the barcode scanner can generate digital data according to the coding rules, and when scanning the barcode, the barcode scanner emits infrared rays, and loses the intensity of a different logic signal according to the intensity of the reflected light, then sends the signals to the barcode decoder for decoding.Barcode Scanner
