A brief introduction to RFID electronic labeling solutions

With the realization of broadband, a freely connected network society is coming. As a basic technology, RFID electronic tag technology has attracted much attention. When all items are equipped with IC chips and connected to the network, item information can be queried and carried out anytime and anywhere. The wonderful future of item management will be easily realized.

RFID electronic tag RFID (Radio Frequency Identification) is one of the automatic identification methods that attaches a tag-like or card-like chip containing information to a person or object and uses radio waves to read and identify it.

Chip sizes range from a few millimeters to several centimeters, and are divided into two types: "passive type" and "active type."

"Passive type" refers to the type that is excited by the radio waves emitted by the reader and writer, while "active type" refers to the type that is excited by the radio waves emitted by the reader/writer.

A type where the built-in power supply emits radio waves to the reader/writer. Keep records from prices to production processes etc.

A chip with a large amount of information is attached to the surface of the product or embedded in the product, and the information is read and updated through a reader.

The main feature of RFID electronic tags is the non-contact operation that uses radio waves to exchange information. The information of multiple IC chips can be read simultaneously through the data reader, that is, the radio wave exchange information, and the "passive type" ranges from several centimeters to more than 1 meter. , "active type" can be read at a distance of several meters; the chip has a larger capacity and can add and update content; in addition, it can read moving objects and is durable and safe (preventing improper copying) , tampering) and other characteristics (please refer to the illustration "Characteristics of RFID electronic tag chips").

RFID electronic label technology can replace product barcodes to achieve more effective product management and improve safety. In addition, it can also be widely used in other fields through connection to the network.

In the medical field, if there are chips on medical devices, drugs and patients, it can improve the efficiency of medical management and effectively prevent the occurrence of medical accidents. In particular, attaching chips to medical waste such as used syringes can effectively Build a medical waste tracking system to improve social security.

In the financial field, if chips are embedded in banknotes, securities or various vouchers, their authenticity can be determined through the Internet and can also be used for settlement.

In the automotive industry, affixing chips to cars can record driving mileage, check maintenance records and car owner information, prevent forgery and tampering of various data, and effectively prevent theft, thereby creating a more convenient, faster and safer purchasing and maintenance environment.

In the supermarket Retail Industry, items with chips can be automatically settled by placing them in the trolley. What is even more interesting is that if your refrigerator can read the chip information on the food and connect to the Internet, it can check the contents of the refrigerator for you. Food management allows you to know the "inventory" situation of the refrigerator in the supermarket and make correct and timely purchasing decisions.

In the tourism industry, if your luggage has a chip, you only need to Store it at the airport and wait at your destination with confidence. The luggage will be delivered safely according to the information in the chip.

In the near future, data readers can also be installed on mobile phones, allowing you to read chips and confirm information while moving.

In addition to greatly changing our lifestyle, RFID electronic tags will also have a more profound impact on business activities.

At the beginning of 2005, Wal-Mart, the world's largest retail owner, required its top 100 suppliers to add IC chips to all goods. The application of RFID electronic tag technology in the circulation field has improved the out-of-stock rate, automated product inspection operations, and ultimately achieved cost savings. Currently, two-thirds of its suppliers are Chinese companies, so it is foreseeable that Chinese companies will soon enter the era of using IC chips.

In the manufacturing industry, it is easier to manage materials and inventory by attaching chips to raw materials and accessories, and the paper subpoenas used in the past can be converted into chips to facilitate managers' macro-control and improve production efficiency. In addition to production, the use of RFID electronic tags can be further expanded in procurement, inventory management, after-sales and other links, so that overall efficiency, quality and CS can be comprehensively improved.

In addition, the application of RFID electronic tags in social public service institutions such as libraries, art galleries and museums can improve the quality and efficiency of services. In Japanese libraries, a comprehensive Library management system integrating IC chips and library Management systems has been introduced (please Refer to the illustration "Integrated Library Management System"). Due to the introduction of IC chips, information such as book titles and authors that could never be recorded with barcodes can be recorded. Rental and return processing can be processed in just 5 seconds through a reader connected to the computer. It can also quickly handle matters such as new book storage and book collection confirmation, effectively improving service quality and efficiency.

In order to make better use of IC chips, the construction of a comprehensive system connected to the network is extremely important. RFID electronic tag systems usually consist of chips, antennas, data readers, information entry systems, information background processing systems, etc. (please refer to " The structure diagram of the RFID electronic tag system"). The function of the information background processing system is to read IDs, query ID data, and exchange large amounts of information through the network at any time. How to manage large amounts of data on the network has become an important topic, middleware and background Processing systems are the answer. The middleware can distinguish and organize various chip information from multiple manufacturers and pass it to the background processing system and production management system to achieve production efficiency.
