Passive smart lock is an intelligent lock that combines the characteristics of mechanical and electronic locks. Composed of a passive smart lock, smart key, and management software, the passive smart lock does not require battery installation and is equipped with an electronic chip that provides reverse power to the passive smart lock through the smart key.

At present, the popularity rate of passive smart locks in China is relatively low, but the application prospects are broad.

Development advantages of passive smart locks:

1. Policy support: In recent years, the country has vigorously promoted the development of the Internet of Things, big data, and new energy, and has successively introduced various industrial policies to guide the orderly and high-end development of the smart lock industry, encourage the transformation and upgrading of the smart lock industry, improve quality and efficiency, and provide a good environment for the development of the smart lock industry.

2. Enterprise independent research and development: In the development and progress of technology, multiple intelligent lock research and manufacturing enterprises have emerged, investing a lot of manpower and material resources in the research and development of passive intelligent locks, achieving good results, and gradually forming their own unique passive intelligent lock products.

3. Reduce enterprise management and maintenance costs: Compared with traditional electronic locks, passive smart locks have no built-in batteries, are maintenance free, and reduce maintenance costs; Automatic upload of lock on/off logs to the platform, intelligent key for one to many unlocking, reducing management costs and improving management efficiency.

4. Wide application range: Currently, passive intelligent locks can be seen in industrial fields such as power, communication, petroleum, customs, logistics, military, railway, banking, and hazardous chemicals.

Challenges faced by the development of passive smart locks:

1. The application places of locks are often outdoors or in environments that require high maintenance free, long-term, and trouble free operation of the locks themselves. Therefore, the requirements for waterproof, dustproof, and rust proof functions of locks will also become increasingly high.

2. Due to the limitations of passive smart locks, more advanced functions are implemented by smart keys, and the future development of smart keys will be more intelligent, which is also a major challenge to the technical strength of enterprises.

Due to the increase in application industries and the diversification of industry application characteristics, the demand for customized management software is also increasing, which puts higher demands on the functionality and stability of management software.

In the future, it is an inevitable trend for high-tech passive intelligent lock systems to replace traditional mechanical locks. Passive intelligent locks are bound to be widely used in various industries and become an indispensable and important component of locks.
