Golden finger code is the veteran of the domestic fingerprint lock industry, which was established as early as 1994, and is also the manufacturer of China's first fingerprint lock, with deep technical accumulation. After Su Xianze, chairman of Supor Group, became the largest shareholder, and other brands established in the same period have disappeared, Jinzhima still survived, which shows its strength. However, in terms of product innovation and market layout, there is still a big gap between Gold Finger Code and other brands.

At present, there are more than 10 fingerprint locks on sale, but nearly half of the products use optical fingerprint recognition technology, which cannot distinguish between real and fake fingerprints, and there are certain security risks. In addition, the gold fingercode fingerprint locks are all real ferrules, although the real and fake ferrules are not the key components that affect the security of the door lock, but the real ferrules do bring difficulties to violent demolition. If there is a dangerous situation, it will take a few more minutes for rescuers to break into the door, and the thief entering the house is basically unlocked by technology, and the real mortise does not help much in improving the security of the door lock.

However, the gold finger code fingerprint lock also has positive aspects, all of which use C-level lock cylinders to ensure basic security. At the same time, almost all of its fingerprint locks are equipped with a unique three-level user management system, which is convenient for users to manage fingerprints and passwords. As the name suggests, the three-level user management system is divided into three different levels of management authority, and the first level user has the highest authority, which can enter, modify and delete administrators; Level 2 is the second, only ordinary users can be entered, modified and deleted; Level 3 is a temporary addition of users.

There are 4 series of finger code fingerprint locks, namely a grip open series, a classic slide model, a simple straight plate model and a luxury villa model, the latter two series of products use optical identification, which has been less used in the market and is not recommended. In the one-grip series, K51, K21, SK1, these three designs are more in line with the current mainstream, all use semiconductor fingerprint recognition, and can be connected with mobile phone APP, the price is between 1500-2700 yuan. The classic slider is more recommended is C5, with a three-level user management system, with a high level of security, and it is also a rare fingerprint lock with anti-cat's eye opening function in the fingerprint lock, which is better than other products. In other aspects, the C5 is also equipped with functions such as hijacking passwords, anti-tampering and anti-trial opening alarms. However, its golden appearance is slightly tacky for some consumers, and the price is around 2,500 yuan.
