Lockin

Lockin is a global smart-lock and home security company that focuses on developing biometric, keyless entry systems for homes and businesses, with a particular emphasis on palm and vein-recognition technology for secure and convenient access. 

Originating under Yunding (Yunding Network Technology) in China, it has grown into an international brand with products and regional operations across Asia, Europe, North America, the Middle East, and Oceania. The company designs and manufactures a range of devices including smart door locks, video door locks, and connected-home security solutions, often combining features such as palm vein recognition, fingerprint sensing, integrated cameras, AI-based detection, and strong mechanical lock bodies that comply with major strength and security standards.
