This is the jewelry box that requires only a fingerprint to grant access to precious items. Eliminating the need to remember combinations or hide a key, a matching fingerprint opens the lock within a second. Panelists from The Hammacher Schlemmer Institute praised the accuracy of the sensor and noted there were no false positives during testing. The flannel-lined, mirrored interior protects jewelry from nicks or scratches and features a hidden compartment for additional security. Stores up to 10 different fingerprints and one administrator print; with a six-month battery life. Recharges via USB. Spare key if box is in low power mode.
