For decades, the theory of RFID technology has been enriched and perfected, and active, passive and semi-passive electronic tags have developed rapidly. Single-chip electronic tags, multi-electronic tag reading, wireless readable and writable, long-distance identification of passive electronic tags, and RFID adapted to high-speed moving objects are becoming a reality.
1. Introduction of RFID tags
RFID tags are widely used in our lives, and RFID tags are also widely used in the Internet of Things, sports competition, air package management and other fields. The built-in RFID tag is a chip, and the built-in chips have their own ID. And each RFID tag has a separate UID label, usually a product is bound to a certain RFID tag (with a unique ID), and they belong to a binding relationship, just like giving a person is assigned a unique ID number, and with the UID, fraud can be avoided.
In the early days, the label did not have a serial number. Later, each label has a unique ID, which can also be understood as an ID number. This unique ID is applied by the manufacturer to an organization, and there will be no RFID label reuse, or when multiple products correspond to one label.
2. Why RFID tags can be used as global unique codes?
First of all, the coding of RFID tags follows certain rules; RFID tags follow the coding rules of EPC. The full name of EPC is Electronic Product Code, which is called electronic product code in Chinese. The carrier of EPC is the RFID tag, and the transmission of information is realized by means of the Internet. EPC aims to establish a global and open identification standard for each single product, so as to realize the tracking and traceability of a single product on a global scale, thereby effectively improving the level of supply chain management and reducing logistics costs. EPC is a complete, complex and integrated system.
Electronic product code (EPC code) is a new generation of product coding system launched by the International Barcode Organization. The original product barcode is only the coding of product classification, and the EPC code is a coding system that assigns a global unique code to each single product, and the EPC code is a 96-bit (binary) coding system. The 96-bit EPC code can assign codes to 268 million companies, each company can have 16 million product categories, and each category of products has 68 billion independent product codes. Figuratively speaking, each grain of rice on the earth can be given a unique code.
From the above, it can be understood that the traditional barcode is not unique, so it is easy to be copied, and it cannot play a real anti-counterfeiting and anti-counterfeiting role. The RFID tag is unique (unique id), cannot be copied, and cannot be faked.
