90% of people will not judge the good or bad of the barcode scanner

When selecting a barcode scanner, the most important thing is to pay attention to the scanning speed and resolution, and the depth of field is not a key factor. Because when the depth of field is increased, the resolution will be greatly reduced. An excellent handheld scanner should have a high scanning speed and a high resolution in a fixed depth of field.

1, scanning method

The scanning method of the barcode scanner is mainly divided into a CCD mask type, a laser scanning type, and an image type.

2, scanning speed

That is, the number of scans per second

3, resolution

Use the mil value to give a nominal (mil). In general, the smaller the value, the better.

4, interface mode

Usually divided into keyboard port (KB interface), RS232 interface (serial port) and USB interface.

How to choose the right barcode scanner

CCD scanners are generally used for occasions where funds are tight and are not suitable for applications such as general convenience stores, clothing and catering.

The gun laser scanner is moderately priced, has a faster scanning speed and higher accuracy, and is used in demanding occasions such as warehouse management and express logistics.

The platform laser scanner is slightly more expensive and easy to use, and is used in applications requiring speed and accuracy, such as Shangchao Department Store, government, and medical industry.
