The Philips 5000 series Wi-Fi Palm Recognition Smart Lock is the World's first palm-recognition deadbolt lock. Innovative palm recognition technology turns your palm vein patterns into a key rather than a surface palm print, offering the newest, faster, moreaccurate, and more secure unlocking experience. Philips' key-less entry door lock with palm recognition offers superior accuracy and a seamless unlocking experience compared to other methods. Unlike surface-based print recognition, this technology identifies unique vein patterns beneath your palm. It remains unaffected by your hands' condition, ensuring reliable recognition regardless of sweaty, dusty, or pigmented hands.
