Eufy Security FamiLock S3 Max uses advanced palm-vein recognition for unlocking, surpassing traditional methods like fingerprints and passcodes, ensuring higher accuracy and security.
The SmartLock is quite big and bulky as travel padlocks go — it weighs about 3.5 ounces — but it combines two functions in one. And that bulkiness gives the padlock a decent level of resistance to physical attack. You're not going to break this with your hands or a small multitool.
