EFLHX800 is a high performance fingerprint door lock designed for universal usage. It's specially designed to resolve the problem of compatibility between the different standards of door and lock. So, it's a universal fingerprint door lock which can be installed for a various types of doors, for new door not yet equipped with lock, or for old door equipped with any type of lock. High manufacture precision and reliability is another strong point of the product. It can be used as office and domestic door lock. The core technology of EFLHX800 is the true skin fingerprint sensor which can sense inner layer of skin (alive skin) instead of top layer of skin (dead skin). The main advantage of the product with true skin fingerprint sensor lies in the high capability to recognize fingerprints under various conditions. Not only it has high recognition rate (very low False Rejection Rate: FRR) for ideal fingerprints but also it keeps high recognition rate for fingerprints from non-ideal fingers, such as dry fingers, light texture fingers, abraded fingers, rough fingers, old peoples' fingers, fingers with oil, dust, and ink, etc. Unlike other products with sensor which detects top layer of skin, EFLXL800 is sensible only to alive human skin so that it prevent fake fingerprint from artificial material.
