Seeing the development of fingerprint lock industry from the core replacement

The development of the fingerprint lock industry has been marked by several key technological advancements, especially in the evolution of core inserts. Looking back at the early stages, the first generation of fingerprint locks was primarily used in hotels and high-end facilities. These early models were heavily influenced by European and American technologies, focusing on both innovation and quality. The hotel insert became a significant milestone during this period, offering a more intelligent alternative to traditional mechanical locks. At that time, these fingerprint locks featured large tongues that could only be controlled from within the room, resulting in limited intelligence. Additionally, the heavy electromechanical collaboration often caused gaps when the lock closed, making it vulnerable to card-based attacks—similar to what is often seen in movies. This weakness significantly compromised security, as thieves could easily bypass the system with a simple card. Despite these drawbacks, the first-generation fingerprint locks were a big step forward compared to traditional locks. They allowed for card-based access, which made management easier and more efficient. This feature made them popular among hotels, clubs, and other high-level establishments, many of which still use these systems today. As the industry progressed, the second generation of inserts introduced the “lifting handle” design. This version improved upon the hotel inserts by refining the mechanical and electrical components, reducing the gap when the door closed and improving overall smoothness and security. Many of these models also incorporated water resistance features, making them suitable for broader residential applications. However, the lifting handle design still had a major flaw: users had to manually lift the handle after closing the door to lock it. This was inconvenient, especially for the elderly or children, who often forgot to do so. As a result, security vulnerabilities remained, leading to numerous reported cases of theft or unauthorized access. To address this issue, the third generation of inserts introduced the “big tongue auto pop-up” technology. Developed by industry leader Dijks, this innovation eliminated the need for manual locking by using a sealed capsule sensing system instead of a motor. This reduced internal friction and enabled the large tongue to automatically extend, providing a seamless locking experience that aligned better with user habits and enhanced security. Although this advancement was significant, the third-generation inserts still had limitations. They could not automatically retract the heaven and earth rods, which left some security gaps. This led to the development of the fourth generation of inserts, known as the multi-point tongue self-propelled model. The fourth-generation inserts, developed by Dijer, took the technology even further. They featured both the large tongue and the heaven and earth rods popping up automatically, significantly increasing the product’s technical sophistication and security performance. This model is currently considered the most advanced in the industry, meeting the growing demand for smart, secure, and user-friendly locks. Despite its advantages, the fourth-generation insert is still relatively rare due to its high technical complexity and cost. Many companies continue to rely on the second-generation models. However, as technology continues to evolve, this advanced design is expected to become more widespread, enhancing the convenience and safety of daily life. Industry experts agree that while current fingerprint lock technology meets many modern needs, there is still room for improvement. To move forward, the industry must focus not only on lock body design but also on optimizing the core inserts. Enhancing the intelligence of the core will help lead the way toward a future where fingerprint lock technology is more precise, reliable, and integrated into everyday living.
