Talking about Radio Frequency Identification Technology

Since 2004, a wave of radio frequency identification (RFID) technology has been launched around the world. Commercial giants including Wal-Mart, Procter & Gamble and Boeing are actively promoting the application of RFID in manufacturing, logistics, retail, transportation and other industries. . RFID technology and its application are in a period of rapid rise and are recognized by the industry as one of the most promising technologies of this century. Its development and application promotion will be a technological revolution in the automatic identification industry. The application of RFID in the transportation and logistics industry provides a new stage for communication technology and will become one of the potential profit growth points of the telecom industry in the future.

RFID technology requires no direct contact, no optical visibility, no manual intervention to complete information input and processing, and easy and fast operation, can be widely used in production, logistics, transportation, transportation, medical, anti-counterfeiting, tracking, equipment and asset management, etc. The areas where data needs to be collected and processed. The RFID system consists of three main components: readers, tags, and other peripherals. Compared with traditional barcode recognition technology, it has the ability to read multiple labels at one time, has strong penetrability, can be read and written multiple times, has large memory capacity, is easy to be miniaturized and diverse, and has environmental resistance. It is widely used in the logistics and transportation industries.

In the logistics industry, RFID technology makes reasonable product inventory control and intelligent logistics technology possible. Its application process in the logistics industry is: each product is shipped with an electronic tag, then a unique identification code is written through the reader, and the information of the item is entered into the database. After that, all the links such as box sales, export verification, arrival distribution, and retail shelves can be read and written repeatedly by the reader. The label is the “ID card” of the item. With the help of the electronic label, real-time monitoring of the raw materials, semi-finished products, finished products, transportation, warehousing, distribution, shelves, final sales, and even return processing can be realized. RFID technology improves the automation of item sorting, reduces the error rate, and makes the entire supply chain management transparent and efficient.

The application of RFID in the transportation industry is mainly in highway tolls and intelligent transportation. By installing a radio frequency identification card in the car, the car can be automatically recognized, and the payment is completed while the vehicle passes through the toll booth at a high speed, thereby greatly improving the driving speed and efficiency, thereby avoiding congestion and solving the traffic bottleneck problem. After the system is connected with the vehicle information database and the payment information database, the non-stop inspection can be automatically performed on the passing vehicles, and the vehicle arrears and violations can be found within a few seconds by comparing with the data center database. Through the use of information technology, network technology to minimize the risk of vehicles escaping traffic costs and illegal operations.

RFID realizes the intelligence of information identification and collection. This is only the first step to achieve efficient transportation logistics in the future. It is necessary to fully utilize the high efficiency of RFID and have the needs of full informationization. It needs the support of other information management systems. How many cargo information can be deployed in a scientific and rapid way, and the application of communication technology in this link has a lot of room to play.

First, the biggest advantage of RFID in replacing barcodes is the wireless identification brought by magnetic stripe and the networking of information. In the field of logistics, the data collected by RFID can only be realized automatically under the large network environment including production, transportation and sales, which requires an open and interconnected network support. Data transmission, sharing, and provisioning can be performed on this network, and functions such as tracking and positioning of goods can be realized by means of wireless technology. In the transportation field, due to its high mobility and the characteristics of a national transportation network, the highway toll system does not require an open and unified network support. The years of network construction and operation experience of communication operators make them uniquely advantageous in the provision of basic service platforms.

Second, the RFID industry requires a third party with extensive experience to integrate and maintain RFID systems. At present, the main obstacles to the development of China's logistics industry are high system costs and lack of efficient process operation management systems. The communication operator has rich experience in commercial data processing. With its wide coverage and high-capacity network resources, combined with the existing GPS positioning and tracking service platforms, it is easy to form an application solution that effectively improves the efficiency of logistics management. Program. The communication network can provide the high-speed, secure and real-time data channel required by RFID. The rich data service of the communication network can meet the needs of different applications of RFID in different fields. The high-performance RFID-enabled communication equipment terminal provided by the equipment manufacturer, we It is believed that the integration of RFID technology and communication system may become one of the directions for the development of the telecom industry in the future. By utilizing the interconnection of future RFID technology with computer network, wireless communication network and satellite communication network, RFID data information transmission, cargo scheduling and tracking can be conveniently realized, and the management center can obtain a large amount of cargo information through the computer network, according to the transportation and distribution links. The replenishment and deployment of the specific situation, the enterprise field personnel can access the data of the internal business system of the enterprise through the communication terminal such as mobile phone, PDA, computer, etc. anytime and anywhere, receive the receipt list and dispatch list sent by the information center, and can also use the handheld The scanner transmits the barcode of the goods to the back-end system in real time to synchronize the flow of goods and information.

In fact, some forward-thinking communications equipment manufacturers and telecom operators have begun to study how to combine RFID technology with existing or future communication systems to develop new services and applications. Foreign telecom operators, including AT&T and BT, have begun to look for business opportunities in RFID operations management. Some AT&T customers are already using AT&T's IP backbone and services to carry out RFID projects. AT&T not only provides customers with a network transmission platform, but also configures their own RFID infrastructure. BT also works with Microsoft's Software Products Base (EMEA) in Europe, the Middle East and Africa to provide RFID service management services to retailer Marks & Spencer.

Since RFID technology conveniently helps warehouse operators and retailers to realize the storage of cargo information, the application of RFID on the existing mobile cellular network enables the reading of cargo information through the combination of mobile device terminals and RFID technology. The functions of anti-counterfeiting, payment, etc. are also one of the potential application markets for operators. NTTDoCoMo launched the Fe-lica mobile wallet service using RFID technology in Japan in mid-2004. This business integrates RFID technology with its PDC and FOMA technologies, and supports Felica's mobile phones (including 2nd generation mobile phones and 3rd generation FOMA mobile phones). Built-in RFID chip, in addition to the payment function, merchants can provide special services such as electronic money and customer points to Felica users by using readers who can read the memory card and the information on the FeliCa chip on the mobile phone and exchange information as needed. .

Looking to the future, RFID technology based on the network environment will create a huge "Internet of Things" between items, between objects and people. The Internet of Things will be the most important technological revolution after the Internet. Combining communication and computer technology, the object communication will become one of the communication methods with great market potential and economic benefits after communication between people. It will be a thorough supply chain revolution and will profoundly affect all aspects of economic and social life. Faced with the rapid rise of the RFID industry, communications companies, including equipment manufacturers and operators, should maintain a keen business sense and actively explore the business opportunities that RFID brings to the communications industry in order to seize the opportunities in the future RFID arena.
