Description

Background
The 21 st century is a century of rapid logistics, and logistics also has the effect of being not worn out in economic development and industrial production in China. On the other hand, with the vigorous development of online shopping in China, the demand for rapid logistics is further promoted to increase, and a large number of expressways are available every day to wait for logistics transportation. On the other hand, however, the logistics transportation industry needs not only fast delivery and efficient transportation to provide low-cost transportation, but also to ensure the safety of logistics transportation, i.e. to ensure safe and lossless delivery of goods and to ensure no loss of goods; however, nowadays, the event of the loss of the logistics goods occurs, so how to ensure that the goods are not lost is a technical problem to be solved by the logistics industry.
Currently, electronic tags are classified into active electronic tags and passive electronic tags. Active tags and use batteries, while passive tags require an external energy source for information transmission. Passive electronic tags are read and/or read-write and are mainly used for object identification; they do not have any processing power in any case. In any event, they cannot communicate with each other and require installation of a reader infrastructure to retrieve the information. To date, all passive and active electronic tags require reading devices to record and obtain information and data. Only recently are communication possible between electronic tags provided that they are provided with a battery, in other words they must be active tags, which makes them expensive compared to passive tags and they have a negative impact from an environmental cost point of view.
The electronic tag produced by the traditional production mode is only subjected to communication transmission through the code of the electronic tag, so that effective management and data record for the tag are lacked in the production process, the data of the electronic tag is only relied on and is easy to be counterfeited, and once the electronic tag is separated from the to-be-distributed article, multiplexing and unified management are difficult to realize, so that the use cost of the electronic tag is improved in a variable mode, the finally improved cost is borne by a distribution service purchaser, and the distribution scheme based on a block chain is difficult to popularize commercially.
In the prior art, an electronic tag manufacturing scheme is adopted, in which a mature coding system such as an electronic product code (EPC code) is used for writing data into an electronic tag, but a tag manufactured by a conventional manufacturing scheme needs a specific reading scene to realize information verification, and under the condition that reading equipment cannot completely read coded data, the electronic tag is misread, and management and tracking of an article through the digital tag are inconvenient in a purely human logistics link.
