TCL D1 Fingerprint Smart Lock offers fast unlocking and local data storage for privacy-focused homeowners


If you’ve been thinking about upgrading your front door with a smart lock but don’t want your data floating around in the cloud, TCL may have the perfect solution. You see, the company has officially launched its D1 Fingerprint Smart Lock, a product designed to make home security both simple and private -- and yes, it is available to buy right now from Amazon for $89.99.
One of the big selling points is speed. The D1 uses a Swedish-made FPC fingerprint sensor with 508 DPI resolution, unlocking your door in just 0.3 seconds. TCL also worked an AI self-learning algorithm into the mix, which means the lock is supposed to get better at recognizing your fingerprint over time, even if your fingers are wet or dry.
