As a contact product of the security and access control industry, it plays an important role in promoting the concept of intelligent and secure security. By integrating some basic information of the security industry in recent years, this paper analyzes the survival and development of the security and access control industry in recent years.

In the traditional security industry, as a part of the security subsystem of the intelligent weak current system, the access control all-in-one card integrates automatic identification technology and modern security management measures, involving many new technologies such as electronics, machinery, optics, computer technology, communication technology and biotechnology, moving towards a high degree of integration, reflecting the requirements of modern intelligent management.

According to relevant data, in China's domestic access control market from 2005 to 2006, the market scale of RFID based access control system was about 2.5 ~ 3 billion, and the fingerprint access control system was about 400 million yuan. According to relevant statistics, there are more than 10000 enterprises engaged in the business of security access control products, including system engineers. The number of enterprises including "access control" in their main business is 2780, including 1447 security alarm access control businesses. The distribution is 3857 in Guangdong, 1452 in Shanghai, 1139 in Beijing, 796 in Jiangsu, 632 in Zhejiang, 366 in Fujian, 349 in Shandong, 203 in Liaoning 205 enterprises in Hubei, etc.

In addition, the market demand for intelligent buildings, factories and mining enterprises, banks and other fields has increased rapidly in recent three years. The industrial chain of China's security access control system products and supporting equipment market has achieved a rapid growth of more than 20% ~ 25% per year. In 2008, the market scale of China's security access control system and supporting (including identity identification smart card and electric lock) industrial chain will reach 18 billion; According to the statistics released by the 11th China International Smart Card Expo, by the end of 2006, the country had issued 3 billion cards, including 1.01 billion mobile phone IC cards, 890 million public phone IC cards, 398 million second-generation resident ID cards, 148 million campus cards, 67 million social security cards, 77 million bus IC cards and 674 million other types of IC cards. By 2008, the average annual issuance of smart cards in China had accounted for 15% of the total issuance in the world. The 2008 China RFID development report released by the national gold card project at the "2009 China International smart card and RFID Expo" predicts that the scale of China's RFID market will be 7.03 billion yuan in 2009, an increase of 20.6% over the expected 2008. At the same time, according to the estimates of relevant experts, the market potential carried by the construction of all-in-one card in only 1792 colleges and universities in China is nearly 6 billion (481 private universities are not included in the statistics). All links of the industrial chain of the access control all-in-one card system, such as RF card, reading and writing machines, electric lock, software and system integration, have also achieved rapid development. On the other hand, radio frequency identification (RFID), as one of the most promising information technologies in this century, has been highly valued by the global industry.
