Before each product is launched, there is a fixed set of production standards and models, and the product code is no exception. Commodity coding must comply with three major principles:
The uniqueness criterion is the prerequisite for the production of product codes, and it is also the core criterion. In the industry POS intelligent summary system, two different products must be distinguished by a unique barcode. If different products use the same barcode, the result will be confusion of product information, and it may also cause a The emergence of a series of illegal sales behaviors is not conducive to the healthy development of the market. Therefore, different products should be assigned a unique and independent product code. Products with the same general form can be regarded as one product, otherwise, they must be regarded as different products. What needs to be especially vigilant is that the general characteristics of a product are the main basis for distinguishing different products. If a product needs to be determined at a price, it is often judged by this. Therefore, this factor is special and the staff must compare it with other general characteristics. Understand separately, such as volume, net weight, etc. To make these features and the form of the product appear together, it is necessary to cooperate with the coding to have real meaning. If the general characteristics of the product are determined, then due to production and other links, a basic factor of the product changes, so the original code of the product should also be changed, and only in this way can it meet the criteria of uniqueness, product information Will be more accurate.
The principle of stability is the consolidation of the principle of uniqueness. Simply put, as long as the general characteristics of the product have not changed, then the barcode does not need to be changed. For the same type of product project, no matter what the production mode, the product code is the same and cannot be changed at will. Analyze the worst-case scenario. Even if the product is discontinued and no longer supplied to the market, the code originally used on the product cannot be used on other products immediately, because the database still contains all the identification knowledge of this product, which needs to be removed. This coding must take at least two to three years.
Three, no definition
The undefined criterion is related to the information security of the product. It means that any letter in the exposed code does not have any information related to the article itself. Once this principle is violated, coding opportunities are easily lost. Therefore, when designing codes, manufacturers should choose codes that do not have any defined content. For some special or designated products, some basic information, such as the date of production or the source of production, needs to be identified in the circulation link, and a specific mark can be used to indicate it to meet the needs of the work.
The above three points are the three main points for the deterioration of commodity barcodes. I hope that manufacturers can strictly comply with them and let barcodes benefit the market.
