first of all, is the code system you use a commonly used code system: such as 39 codes, 128 codes, Ean-13 codes, etc., special code systems, general code scanning equipment may not be turned on when leaving the factory; in the case of ensuring the normal code system, if you have other code scanners on hand, you can use another code scanner to check. if it still cannot be recognized, it’s time to find the problem from the barcode label! common possible factors:

1、if the barcode is reduced to a very small ratio during production, it will be difficult for a general scanner to recognize it.

2、the printed barcode is not clear enough or has breakpoints, which makes it difficult to scan, as follows:

in addition, if the 39 code is used, the numbers must be added before and after *only by assigning a value again can it be identified.
