On the impact of electronic labels on China's label industry

what is electronic labels

electronic labels realize automatic identification through radio frequency identification system, store commodity information on the chip and attach it to the surface of the object to be identified. When commodities enter the reading range of the reader, the reader looks for them by transmitting signals. When the signals activate the electronic labels, the latter will immediately feed back the reflected signals carrying the label information, Realize contactless reading and identification of electronic data stored in electronic labels, and achieve the purpose of automatic identification of objects. 1. Regular patrol inspection must be carried out (about 310 task days of normal application)

technical characteristics of electronic labels

at present, anti-counterfeiting labels commonly used in domestic and foreign markets include bar code labels and laser anti-counterfeiting labels. Due to some defects of bar code labels, enterprises in various countries have been looking for an updated and more perfect information solution, and radio frequency identification (RFID) electronic labels came into being. As the electronic version of bar code labels, electronic labels have more advantages that bar code labels do not have. ② after the formal production of products:

1. It can be recognized from a long distance.

bar code labels generally read information through close-up handheld photoelectric devices. Because of the use of radio frequency identification system, the recognition distance of electronic labels also changes with the change of working frequency. Generally, the identification distance of low-frequency RF systems is relatively close, generally from a few centimeters to tens of centimeters, while the identification distance of high-frequency and ultra-high frequency systems is relatively far, from a few meters to tens of meters

2. There is a large amount of information, which can be changed dynamically

the electronic label is based on an area of less than 1 μ M chips to record commodity information, and the amount of information stored in these tiny chips is very large. Manufacturers can define the storage capacity of each type of product and the number of bytes of each sector according to their own needs of this kind of plastic wood composite material, which is a kind of green environmental protection material that saves energy and protects the environment, and the sectors can be read and written repeatedly (read unlimited times, write 100000 times), so that the label content can be dynamically changed, such as the way of storing goods from the origin to the transportation process, storage information, validity period, etc, It is also convenient to modify the original information

3. batch recognition

bar code labels must be scanned in a straight line, with slow reading and writing speed, and can only be recognized one by one. The electronic tag adopts anti-collision technology, which has fast reading and writing speed, and can identify multiple targets synchronously. Non static state recognition, which can recognize up to 100 at the same time per second

4. Higher security

the electronic label adopts an internationally unified and non repeated 8-byte identification internal code, and the access of label data is password protected, excluding the replicability of bar code labels and laser anti-counterfeiting labels. It has higher security and data security

5. Good physical properties

electronic labels have diverse, ultra-thin shapes and good flexibility, and can be easily embedded or attached to products of different shapes and types. The electronic tag has excellent performance of waterproof, antimagnetic, high and low temperature resistance, and can be bent. It can adapt to various working environments and working conditions, and can work in harsh environments such as oil stains and dust pollution. It has a long service life and can generally provide services of more than 10 years

impact of electronic labels on labels in China

electronic label technology has developed rapidly since the 1990s, and soon has been popularized in commodity circulation, production management, transportation and other fields. According to relevant authoritative statistics, the worldwide sales of RF products were US $81 million in 1989, US $141 million in 1992, US $433 million in 1997 and US $685 million in 1999. It is expected that the sales of electronic labels, readers and related software and services will increase to US $3billion by 2008. It can be seen that electronic labels have broad market prospects

in addition, the mandatory requirements of some foreign companies on electronic labels have also forced the bar code labels commonly used in China to abdicate and cede market share to electronic labels

application status of electronic labels

radio frequency identification technology is the most advanced non-contact induction technology at present. In 2000, the international organization for standardization has written this chip into the international standard is015693, and radio frequency identification technology has developed rapidly all over the world. RFID technology has been widely used in many fields, such as automated production lines, commodity picking systems, transportation control and management, logistics supply chain, security and anti-counterfeiting, military and so on

at present, the technology of RFID crystal melting point ≥ 280 ℃ has developed rapidly abroad. There are many kinds of electronic label products, such as Texas Instruments, Motorola, Philips and other world-famous manufacturers produce electronic label products. China started late in this regard, and the electronic label market is still in its infancy. From the current development of electronic label technology, there are still many problems to be solved and improved

1. High cost

at present, the cost of electronic labels is at least 30 cents per piece, and the cost of sensors is higher, up to 1000 dollars. If you want to add electronic labels to every item in the store, the label cost must be reduced

2. High error recognition rate

the identification signal of electronic tag is likely to be interfered by wireless, wireless local area network and other communication equipment. It is reported that at present, the error rate of electronic label product identification has reached 20%, which is still a certain distance from a large number of commercial applications

3. There is no unified standard specification

there is no unified standard specification for the application of RFID technology in China, and the RFID equipment of various companies is very different, resulting in the realization of information sharing and transmission, which hinders the development of logistics informatization

electronic label is the product of the rapid development of modern science and technology. It meets the needs of social development and is also the trend of label development in the future. At present, China is still relatively backward in RFID technology, which is only applied to low-frequency and intermediate frequency products. For the vast majority of enterprises, this advanced management method and technology has just started. It is expected that in a long period of time, the mature bar code label technology will not die out, and bar code labels and electronic labels will grow and fall, forming a trend of coexistence and common development of both
