Barcode rules:

1. Uniqueness: the same product with the same specification corresponds to the same product code, and the same product with different specifications should correspond to different product codes. According to the different properties of products, such as weight, packaging, specifications, smell, color, shape, etc., different commodity codes are given.

2. Permanence: once the product code is assigned, it will not be changed, and it is lifelong. When this product is no longer produced, its corresponding product code can only be shelved and cannot be reused and redistributed to other commodities.

3. Meaningless: In order to ensure that the code has enough capacity to meet the needs of frequent product updates, it is best to use meaningless sequence codes.
