The thickness and distance of the barcode are different from the code system of the barcode.
The code of the barcode of general products is EAN
13 code. The contents of the barcode are the numbers below.
It is to facilitate the manual input when the barcode cannot be brushed in.
If there is a corresponding relationship, the computer is scanned from the warehouse! If you only have the code, you cannot check the product information in different places!
The barcode represents the number, which is the graphic format of the number for scanning; if the scanner is not a scanner, you can manually enter the number below!
The contents of the above barcode scanned to the computer are the numbers below. The number number unlocked by the barcode is used to represent the product, which is convenient to manage, eliminates manual enrollment, and reduces errors. Numbers can be hidden.
