How to choose Barcode scanner

The selection method of barcode scanning gun

1、Choose according to barcode density and barcode type

The smaller the density of the barcode, the higher the accuracy requirement of the barcode scanner, If the code density less than 5mils, you need to use a high precision scanner, otherwise it may not be recognized.

Generally speaking, the 1D barcode scanning gun can only scan 1D barcode, and the 2D barcode scanning gun can scan both 1D barcode and 2D barcode, of course, the price will be more expensive, and the barcode that needs to be scanned in the actual application is different, and the choice will be different.

2, according to the scanning distance and whether to edit to choose

The scanning distance of the barcode scanning gun is also its key parameter, if the distance is too far, more than 1 meter, you need to choose the barcode scanning gun with a larger depth of field.

For whether the scanned data needs to be edited, such as only taking the first seven bits of scanned data, you need to choose the scanning gun that can provide corresponding technical support, and the ordinary scanning gun does not support this function.

3, according to the interface and barcode quality to choose

The interface of the barcode scanner gun has USB interface, serial port, etc. The default is USB interface, USB interface is simple and convenient, plug and play, especially for notebooks and desktop computers.

Red light scanning gun for low contrast barcode and barcode quality is not good, as well as the barcode surface lamination, red light still has an advantage over the laser. Laser barcode scanning gun has the advantages of high success rate of first reading recognition, recognition speed, very low false code rate, good shock and fall resistance, but the price is also more expensive. Two kinds of scanning guns have their own advantages, according to the actual situation to choose.

4, according to the scope of use and use of environmental selection

Bar code scanning gun is divided into wired and wireless, wireless scanning gun is also called cordless scanning gun, can use Bluetooth or wifi way to transmit data. Bar code scanning gun has a certain industrial grade, if used in a harsh environment, you need to use industrial grade high equipment, ordinary office or supermarket, choose the ordinary can be.
