Number combinations can be stolen. Face ID and fingerprints can both be spoofed. And if those are stopping you from adopting a smart door lock, well, TCL is offering a new biometric unlocking solution that may make you change your mind. Folks, meet the TCL D2 Pro Palm Vein Smart Lock.
You read that right. This smart lock unlocks by scanning the veins in your palm. Our palms contain a unique network of veins beneath the skin. Just like fingerprints, no two people have exactly the same pattern. Well, at least that’s what we understand medically.
Anyhoo, how it works is it uses near-infrared (NIR) light to illuminate your palm. Blood that contains deoxygenated hemoglobin absorbs infrared light; therefore, the veins appear as dark lines against the surrounding tissue, which reflects light. This contrast allows the unique palm vein pattern to be captured and converted into a digital template, allowing it to be compared against previously enrolled templates.
The TCL D2 Pro Palm Vein Smart Lock boasts an advanced palm vein recognition system with AI learning that promises 99.99% accuracy and super-fast 0.3-second recognition. The AI learning allows the system to adapt to subtle changes in a user’s palm vein patterns to ensure seamless access while minimizing false positives.
Moreover, this system will not discriminate based on age or skin color, nor will it be bothered by the condition of the hand. So whether you are young or old, tanned or fair, or have wet or soiled hands, it can unlock as long as the palm vein pattern matches.
As far as security goes, the data is stored locally, eliminating the risks associated with remote servers.
In addition to palm vein unlocking, the device also offers a bunch of other ways to unlock, including a FOB, keypad, app, physical keys, as well as voice control through Alexa or Google Assistant.
Speaking of keys, unlike most smart locks, where the physical key is merely a backup, this device makes it one of the primary ways of unlocking. But it also brings about something that may irk some style-conscious users: an obvious keyhole right smack on the device.
The companion app also offers 24/7 remote access, letting guests in remotely, revoking access, checking the door’s status, and managing users. The app also provides real-time notifications. It uses built-in Wi-Fi to connect directly to your home network.
Aesthetically, it has contemporary lines, and the aerospace-grade aluminum construction not only offers a premium look and feel but also durability. Speaking of durability, the D2 Pro is IP55-rated for dust and water resistance and supports a wide operating temperature range, from a freezing cold -25°C (-13°F) to a sizzling hot 70°C (158°F).
The compact unit also packs a massive 10,000 mAh battery, affording up to 10 months of operation.
Finally, like a true smart lock, it features auto-locking, so you can leave and simply close the door behind you. No more worrying about whether you locked the door or not.
If anyone’s interested, the TCL D2 Pro Palm Vein Smart Lock is currently available at a discounted US$152.99 on Amazon.com (U.P. US$169.99).
