Although the one-dimensional bar code we use is the earliest and most widely used smart package, and also the smart package that we have the most daily contact with, we are now able to use it widely in food, medicine and other retail products.

RFID Technology and Labeling RFID RFID technology is a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work can be performed in various harsh environments without human intervention. RFID technology can identify high-speed moving objects and can simultaneously identify multiple electronic labels, the operation is quick and easy.

Tag : Coupled components and chips, each RFID tag has a unique electronic code, attached to the object to identify the target object, commonly known as electronic tags or smart tags. RFID tags are divided into active tags, passive tags, semi-active semi-passive tags.

The working principle of RFID is that after the tag enters the magnetic field, it receives the RF signal from the reader and sends out the product information (PassiveTag, passive tag or passive tag) stored in the chip by the energy obtained from the induced current or sends some Frequency signal (ActiveTag, active tag or active tag); The reader reads the information and decodes it and sends it to the Central Information System for data processing.

At present, RFID radio frequency is mainly used in the logistics chain management and the Internet of things. Because RFID tags are non-contact tags, they are the preferred labels for the positioning of goods in the logistics chain management and are also the preferred labels for item diversion management. It is estimated that RFID technology will be widely used in courier and postal services, air transport industry and enterprise internal logistics management.

Variable data bar code Variable data bar code is a novel anti-counterfeiting technology, its use is in the process of trademark printing given a trademark of a unique data bar code, and the bar code data through the Internet to the designated special database, the trademark The enterprise uses the above-mentioned data barcode to scan the already-used trademark data by using a special scanning device and upload the above-mentioned specified database for corresponding data binding.

Consumers using a product with a variable data barcode just scan once using a smartphone and upload the above specified database through the Internet for proofreading. If it is already bound data, the authenticity of the product can be determined, and at the same time, The database is about to eliminate the binding data to prevent the variable data bar code anti-counterfeit trademark is re-used. Such smart packaging technology will be widely used in the anti-counterfeiting technology of luxury goods and luxury goods.

Other smart tag two-dimensional code is also a widely used smart packaging technology, and one-dimensional bar code (referred to as one-dimensional code), a greater information capacity and security, has now been recognized by the market and widely used, through An ordinary smartphone, "Sweep" can get the QR code of the relevant information.
