Brand new, unused. As you know, fingerprints are unique to each individual. Your one-of-a-kind fingerprint provides stronger security than a series of numbers or an alphanumeric password. This fingerprint authentication mini-camera allows you to register your fingerprint. Data can only be accessed via fingerprint authentication, making it a product that creates data inaccessible to others. With its fingerprint authentication system, unlocking is as simple as placing your finger on the sensor. No more tedious password entry on your computer. Plus, it's compact and palm-sized. It's easy to carry in your pocket. For those who are security-conscious and absolutely do not want their data seen by others, protect your data securely with your own fingerprint! ● Size Width 34 x Depth 12.8 x Height 91.2 (mm) 【Weight】37g ● Supported OS Windows 8, 7, XP (XP is not supported). ● Interface USB 2.0 【Accessories】Main unit, miniUSB cable, simple Japanese instruction manual 【Recording Files】Video: 640x480 30fps AVI format (approx. 33MB per minute) Still Image: 1600x1200 approx. 2 million pixels JPG format Audio: WAV format ● Recording Time Video: approx. 300 minutes Still Image: approx. 40000 photos Audio: approx. 960 minutes 【Internal Memory】8GB 【Expandable Storage】Up to 32GB TF/microSD card 【Operating Temperature】 -20℃ - 50℃ 【Charging Time】approx. 1 hour ● Package Size Width 157 x Depth 96 x Height 45 (mm) ● Weight (including package) 184g
