RFID technology is maturing from ticket to publication

In recent years, with the continuous improvement of RFID technology, the cost of electronic tags has been continuously reduced, and the application fields have also been expanding year by year, such as single-chip electronic tags, multi-electronic tag reading, wireless readable and writable, and long-range identification of passive electronic tags. Radio frequency identification technologies and products that adapt to high-speed moving objects are becoming a reality and moving toward applications. Since RFID technology and products gradually entered the commercial application stage in the late 1990s, RFID (Radio Frequency Identification) technology (also known as electronic tags, radio frequency identification) has received increasing attention, and RFID product types have also become increasingly abundant. Active electronic tags , passive electronic tags and semi-passive electronic tags have all been developed.

Recently, according to experts from the Institute of Telecom Research of the Ministry of Industry and Information Technology, RFID has become the most widely used application in the Internet of Things market today, being promoted to be the third largest application market in the world, and the share of electronic payments has reached 24.9%. The application of RFID technology has already been verified in various large-scale conventions and exhibitions. From the 2005 Aichi World Expo, the 2006 World Cup, to the 2008 Beijing Olympic Games and the 2010 Shanghai World Expo, RFID technology has been widely used in ticketing systems. While enabling large numbers of visitors to enter the market quickly, they also played an anti-counterfeiting role by embedding RFID chips.

RFID technology is not only used in the ticket system, but also introduced into the news publishing industry. The author noted at the Shanghai International Printing and Packaging Products Fair in July that the Changning District Library in Shanghai has successfully introduced RFID (Radio Frequency Identification) technology and moved it to the exhibition site for visitors to experience it. Simply put, readers only need to put the book to be borrowed into the RFID self-service borrowing system, and then scan the RFID reader's card in the RF area. The computer screen will automatically display all the book information. The reader presses the “Confirm” button. Successfully borrowed books.

Coincidentally, the Guiyang Library also successfully introduced RFID technology this year. In its 24-hour self-service library, readers only need to use an RFID lending card to scan in the sensing area, just like accessing money on an ATM. Like books, of course, this does not have to pay any fees.

Looking around the world, the London History Museum plans to use RFID technology to its fullest extent. On August 16, 2011, the museum and Nokia began to test a system through which NFC mobile phone users can get from two NFC RFID tags in the museum. Coupons, exhibits, reservations and other information. Although there are few NFC-enabled mobile phones on the UK market, and only a small part of the population has such products, it is believed that with the growth of NFC mobile phone market and applications, this technology will be inseparable from mobile phone users. The London Museum is full of embarrassment.

In addition, the introduction of RFID technology not only simplifies the traditional borrowing process, making people's lives more convenient and faster. At the same time, if electronic tags are embedded in books and audio-visual products, copyright protection and piracy prevention can also be enhanced, which will facilitate the systematic management of the production and transportation process, and be convenient for publishers, book sellers and consumers. Electronic label products can be tracked and verified at any time in real time.

However, although RFID technology has made breakthrough progress at home and abroad and is gradually replacing traditional publication barcodes, the high cost has obviously become a roadblock that restricts its further development, compared to barcodes that cost only a few cents or even a few cents. It is a "luxury". The person concerned said: "With RFID tags, the information reading distance is about 30-40 meters, and the ex-factory price is between 10 yuan and 20 yuan. If a supermarket labels each item, Definite loss."

It can be seen that the application of RFID technology is not easy. How to break through the cost constraints and allow electronic labeling technology to “take off the noble uniforms and enter the homes of the common people” will be the most important thing in the future, but no matter which way With so many hardships, the replacement of traditional barcodes with electronic labels will be an inevitable trend!
