The concept of one thing, one code has been available for many years. Looking at this concept, Baidu Baike’s definition is 'one thing, one codeSo as to provide a comprehensive solution of O2O marketing, anti-counterfeiting traceability, warehousing logistics and other solutions. Encountered a customer asking how does the printer industry define one thing and one code? In simple terms, this definition is to correspond to a unique code for each physical object. Isn't this definition better to understand? One thing one code was actually applied in the production and circulation of medicines in the early days. The food and beverage industry probably only started large-scale application the year before. Now that the technology of one thing, one code is very perfect, it depends on what the brand/manufacturer needs to achieve one thing, one code to implement it? May be used for marketing, anti-counterfeiting, traceability or warehousing logistics. Customers will ask this question. On the one hand, they are concerned about one thing and one size. From the two aspects of cost and benefit, manufacturers need to consider cost and benefit, that is, the input-output ratio. What's more, it is necessary. For example, national mandatory regulations in the pharmaceutical and food industries must be implemented. The main direction is still on channeling prevention, Internet of Things and marketing. Drugs are transported and packaged in a box as a unit, and anti-channeling and IoT applications can be realized simultaneously through the method of one item and one code in the outer box. From the point of view of the inkjet printer industry, one thing, one code is divided into four major application directions: traceability, anti-counterfeiting and anti-channeling, marketing, and Internet of Things. The inkjet printer industry also knows that the key to the implementation of one object and one code is variable code assignment. Equipment + site identification system + software platform are indispensable.
