A barcode reader is a device used to read the information contained in a barcode and belongs to an input device.

Bar code readers are also called bar code scanners and bar code scanners. They are a device used to read the information contained in bar codes. In computer input and output devices, both it and the keyboard are input devices.

Can be divided according to different light sources

Avision barcode reader (also known as CCD scanning gun) and laser barcode reader.

Laser barcode readers are superior to Aurora barcode readers in terms of scanning speed, scanning distance, and scanning sensitivity. The main application in the market is laser barcode readers.

Laser bar code readers are single-line scanners that use laser diodes as the light source. There are two types of rotary scanners and dithered mirrors. The rotating mirror type uses a high-speed motor to drive a prism group to rotate, so that the single-point laser emitted by the diode becomes a line. The production cost of the tremor mirror type is lower than that of the rotary mirror type, but the laser gun with this principle is not easy to increase the scanning speed, generally 33 times / second, and the highest can reach 100 times / second.

CCD rainbow barcode reader uses the principle of photoelectric coupling (CCD) to image the barcode printed pattern and then decode it. Its advantages are: no shaft, motor, long life; cheap.

According to the application and the type of barcode can be divided into:

Wired barcode scanner (1D, 2D);

Wireless barcode scanner (1D, 2D);

Scanning platform.

Reliable and accurate

There are data to check that the keyboard input is an error every 300 characters on average, and the data is entered by scanning a barcode, and an error is 15,000 characters on average. If the check digit is added, the error rate is 1 in 10 million.

Fast data entry

With keyboard input, a typist who types 90 characters per minute can input 12 characters or strings in 1.6 seconds, while using a bar code, it only takes 0.3 seconds to do the same work, and the speed is increased by 5 times.

Cheap

Compared with other automated identification technologies, the cost of popularizing and applying barcode technology is lower.

Simple equipment

The bar code symbol recognition device has a simple structure and is easy to operate without special training.
