Most smart locks still make you fumble with codes or keys like it’s 2015. TCL apparently got tired of watching people struggle and decided to slap some actual future tech on their doors. Their new Palm Vein Smart Lock reads the veins in your hand. Not your fingerprint. Your actual veins.
The thing uses near-infrared technology to scan blood vessel patterns beneath the skin. Good luck spoofing that, wannabe burglars. It’s contactless too, which means no grimy fingerprint pads collecting everyone’s germs. Just wave your palm like you’re blessing the door, and boom – you’re in. Takes about a second. The palm reader works from 2 to 6 inches away, giving you plenty of room to casually wave at your door without awkward positioning.

TCL threw in basically every access method known to mankind. Palm vein recognition handles 50 different users. There’s a keypad for codes, NFC fobs, a regular key for the paranoid, and smartphone app control. Oh, and it works with Alexa and Google Home because apparently shouting at your door to open is now normal behavior.
The hardware doesn’t mess around either. IP54 weatherproofing means rain won’t kill it. The deadbolt mechanism fits standard doors, nothing fancy required. It survives temperatures from -4°F to 140°F, which covers everywhere except maybe Mercury. The 7800mAh rechargeable battery lasts ages between charges, and there’s emergency power backup when you inevitably forget. The battery runs for approximately six months before needing a recharge.
Privacy nuts will appreciate that biometric data stays on the device. No cloud servers storing your vein patterns next to your embarrassing search history. The app lets you manage users, check who’s been coming and going, and access remotely when the delivery guy shows up. Unlike typical wireless devices, this wired installation offers enhanced security protection against jamming attacks that plague most smart locks.
At $199.99, it’s priced like other high-end smart locks, except those don’t scan your circulatory system. The contactless design means grandma with arthritis can use it just as easily as germaphobe teenagers. No touching required, no spreading whatever plague is trending this week.
TCL basically looked at every annoying thing about current smart locks and fixed them. Sure, reading palm veins sounds like sci-fi overkill. But when it works this smoothly, who’s complaining? Welcome to 2024, where your blood vessels are your house keys.
