Since fingerprints are unique to each individual, this method provides high security. Users register their fingerprints in the app, and then can quickly unlock the key box with a simple touch, which makes it difficult to imitate by others.Password Protection: The key box is equipped with a touch-screen keypad with a backlight and anti-peep virtual password functionality (usually 6 - 9 digits). Users can set a preset password to unlock. The anti-peep virtual password feature allows users to enter additional random digits before and after the actual password, making it difficult for onlookers to figure out the correct code. IC Card Unlocking: It supports IC cards, and multiple cards can be registered in the app. The use of IC cards provides a contactless access method. The card-reading mechanism in the key box is designed to prevent card data from being stolen or copied, and only cards registered in the system can be recognized and unlocked. Mobile App Control: The TTLock app, available for both iOS and Android devices, is the core control interface for the KB2. The app uses advanced encryption technology, such as AES encryption, with a security level equivalent to that of online banking, which is basically impossible to crack. Through the app, users can remotely lock and unlock the key box within the Bluetooth range, and set different types of passwords, such as permanent, timed, cyclic, and one-time passwords, and send them to the people who need them. The app also allows users to view detailed access logs to understand who has accessed the key box and when.Durable and Anti-Theft Design Material Quality: The KB2 is usually made of high-quality zinc alloy, which has high strength and hardness, and is not easy to be damaged by external forces. It can effectively resist prying and theft, protecting the safety of the keys inside. Seamless Design: The key box adopts a seamless embedded design, which can prevent thieves from inserting tools into the gap to pry open the box. This design also makes the key box more waterproof, dust-proof and weather-resistant, suitable for various outdoor environments. - Power-Off Protection and Monitoring - Battery Backup:The key box is usually equipped with an internal battery, such as 3 AAA batteries, which have a long battery life. Even if the external power supply is interrupted, the key box can still work normally to ensure the security of the stored keys. The app can monitor the battery status in real-time and notify the user in advance when the battery power is low, so that the user can replace the battery in time to avoid being unable to open the box due to power failure. - Emergency Power-on:  In case the battery runs out of power, the key box is usually equipped with an emergency power-on interface, such as a Type-C cable interface. Users can use an external power source to supply power to the key box to unlock it and get the keys inside.
