The CCD Bar Code Reader uses one or more LEDs to emit light that covers the entire bar code. The image of the barcode is transmitted to a row of photodetectors, sampled by each individual photodiode, and the detection result of the adjacent detector is "black" or "white" to distinguish each strip or space to determine the barcode. In other words, the CCD reader does not pay attention to reading every "strip" or "empty", but rather the entire portion of the bar code and converts it into an electrical signal that can be decoded. Compared with other readers, CCD readers are cheaper, but the same is true for reading barcodes. It weighs less than a laser reader and is not as accessible as a light pen.

principle of scanning :
1500 Point ccd Image Sensor
Manually / Continuous / Automatic
Depth of scan field
Less than 1/5 million
The CCD Bar Code Reader uses 1500 piexl sensors and 32bit cpu, which can easily read 4mil barcodes and wide barcodes around 10cm, which is very cost effective.
It uses a 32-bit processor with a scan speed of up to 270 times per second and a scan depth of 25 cm.
It has 2 working modes, manual and continuous, and the barcode scanner bracket is optional.
It reads 1d linear barcodes from mobile device displays and paper.
It uses 1500 pixel imaging technology, supports 4mil small bar code, and the detachable cable is easy to replace and switch interface.
It is ergonomically designed to maximize productivity.
