Radio Frequency Identification (RFID) is an automatic identification technology that emerged from the 1990s and matured. It uses radio frequency for contactless two-way communication to achieve identification purposes and exchange data.
RFID technology features
◆The world's only ID anti-counterfeit chip, can not be modified, can not be copied;
◆Flexible installation method ensures that the chip is not removable and cannot be transplanted;
◆ Easy to realize the source trace of the product (which manufacturer produces, which channel purchases, sales);
◆ Handheld reader can realize batch and manufacturer authenticity check in any access to the Internet network;
◆The chip has built-in 96bit or larger storage space, which can be written into the manufacturer's customized information and can be encrypted.
◆ Long-distance reading can be realized through the reader, the fixed reader is 7~12 meters, and the handheld reader is about 2 meters;
◆ The number of labels for batch picking up to 100 or more within 1 second can speed up the logistics operation;
◆ Improve the existing warehousing process of the enterprise, which can realize automatic reading and closing of the warehousing and automatic statistics;
◆ RFID data can be connected to the existing application system of the enterprise.
At present, RFID technology has made breakthroughs in anti-counterfeiting applications.
Internationally, RFID tags can be embedded in standard passport covers or documents in terms of passport security and electronic wallet. The chips provide security functions and support hardware encryption, which conforms to the international standard of ISO 14443. Domestically, there has been a considerable application in this field. The promotion and application of the second generation ID card is a typical representative in this respect.
In this regard, some applications urgently need RFID technology, such as the use of RFID electronic tickets instead of traditional manual tickets to improve efficiency, such as trains, subways and tourist attractions, or to compare the number of tickets in competitions and performances. In large cases, RFID technology is used to protect tickets. Not only does it no longer need manual identification, it can realize the rapid passage of personnel, and it can also identify the number of times the tickets are used, so as to prevent the tickets from being stolen and used again, so as to achieve "number of anti-counterfeiting".
● Drug anti-counterfeiting
According to the World Health Organization (WTO) Geneva Communiqué, more than 10% of the drugs sold worldwide are counterfeit drugs. OTC drugs are special products that consumers can directly purchase. If they are fake and shoddy products, they will seriously affect the health of consumers and even endanger life. . Radio frequency tags provide a label for drugs that can hardly be copied. Any bottle that has been reported to have been lost or has been sold will leave a record on the chip. The US Food and Drug Administration will work with several major pharmaceutical companies to add micro-antennas to vials to use RFID technology to prevent counterfeiting.
In order to combat counterfeiting, the US manufacturer of the anesthetic OxyContin announced that it will use radio frequency technology (RFID) on the vials. Realize electronic monitoring of the entire process from the production to the pharmaceutical factory. The Chinese government has also begun to use RFID technology to achieve their needs with the help of leading manufacturers in the field of radio frequency identification (such as Yapu Finove).
In addition to the anti-counterfeiting function, the RFID tag also has non-contact identification, which can recognize high-speed moving objects, resists harsh environments, has strong confidentiality, and can recognize multiple recognition objects at the same time.
