From The Verge: Anker’s smart home arm, Eufy, has announced its first smart lock that uses palm vein recognition to unlock your door. The $399 FamiLock S3 Max is also a video doorbell with a 2K-capable camera and an interior screen that shows a live video feed through the door lock. The S3 works over Wi-Fi 6 and supports Matter for integration with most smart home ecosystems, including Apple Home and Amazon Alexa.
Palm unlock is a new biometric feature on residential locks, joining fingerprint unlock and facial recognition as new ways to access your home. Philips, TCL, and TP-Link Tapo all recently launched models that unlock by waving your hand over an infrared sensor. Research shows that palm vein recognition is more accurate and secure than fingerprint readers, in part because it works by recognizing that blood is flowing through your veins.
Most people who want a smart lock for their home probably aren’t worried about James Bond-style villains swiping their dead fingers, but there are practical reasons families might find palm unlock a better fit. Some younger kids and those with older hands can find fingerprint readers finicky, and a hand wave requires less precision than hitting a small fingerprint reader. However, it does requires your hand to be free, which the other new unlocking method, UWB-unlocking (which reacts to the presence of your smartwatch or phone), doesn’t.
