Biometrics is a technology that uses biometrics or behavioral characteristics to identify individuals based on the characteristics of "everyone is different, unchanged for life, and carried around" according to the biological characteristics of the human body. There are two types of biometric identification: the first is biological characteristics: fingerprints, face shape, palm prints, iris, retina, pulse, and auricle; the second is behavioral characteristics: signature, voice, keystroke, etc. And fingerprint recognition technology is the most mature branch of biometric technology, and it is also the most widely used technology.

For many years, human beings have been making unremitting efforts to commercialize fingerprint recognition technology by using the latest technological methods they have mastered. Since the 1970s, with the development of computer technology and the maturity of CCD image acquisition technology, commercialized fingerprints The discriminator began to appear. Since 2000, with the innovation of the global information industry, fingerprint identification technology has reached a high level and is widely used in the civilian and industrial markets.

Wireless access control technology gradually matures

Since the birth of wireless access control products, through the continuous evolution of technology, products using FSK, GPRS, Bluetooth, and other transmission methods have emerged. With the rise of Internet of Things technology, Internet of Things access control products have received widespread attention in the security industry.

The wireless Internet of Things access control system can directly replace the existing wired or non-networked access control system. For office building systems, the application of wireless Internet of Things access control can significantly reduce construction workload and reduce usage costs; for hotel systems, it can improve the level of intelligence of access control. But for any new things, there will inevitably be some doubts in the market. How to dispel users' worries about the stability, reliability, and security of wireless systems is the biggest problem in market promotion. We believe that with the promotion of the Internet of Things technology and the development of wireless Internet of Things access control cases one by one, the wireless Internet of Things access control system will surely be more and more popular among users.

Mobile phone card is booming

The mobile phone card is a new technology application that has emerged recently. Its emergence has received positive responses from a large number of businesses and users, and the projects that have already been applied have also begun to show results. Of course, as a new technology, it still has some shortcomings that need to be further improved.

Mobile phone card (rfid-sim card) After nearly two years of development and trial, the application of access control, attendance, consumption and other subsystems is becoming more and more mature and stable, and the application requirements of customers are more and more detailed and diverse. Therefore, the development of the latest mobile phone card launched by China Mobile will rely on the previous rfid-sim internal consumption, attendance test and access control system, so that parking management and water control can be implemented in recent projects such as more application subsystem development, so that the mobile phone card application range is more extensive. For example, for parking lot management, car owners will be able to use their mobile phones to swipe cards and pay by mobile phones. Through the multi wallet feature of mobile RF-SIM card, it can meet the parking requirements of a mobile phone in multiple parking lots under different management. In addition, China Mobile will launch standardized functions such as parking space query and mobile phone reservation in the future. Due to the convenient use of mobile phone card, many security manufacturers have begun to develop one card technology, hoping to occupy an acre of land in the future market.

The technology of the access control industry is changing with each passing day, and companies are constantly developing corresponding technologies based on actual market demands to meet market demands. The article only mentions smart cards, biometrics, wireless access control and other related technologies. In fact, with the continuous development of technologies in other fields of society, other technologies in the access control industry are also constantly being developed and updated. I believe the access control industry will develop better in the coming time.
