The TCL D2 Pro Lets You Open Your Door Like Iron Man
If you’ve ever wanted to unlock your front door with a move straight out of Iron Man, TCL’s new D2 Pro Palm Vein Smart Lock makes that fantasy surprisingly real. Instead of typing a code or pressing a fingerprint sensor, you simply raise your hand—repulsor-blast style—and the door unlocks in 0.3 seconds.

The magic comes from TCL’s AI-driven palm vein recognition, which scans the unique pattern of veins inside your hand. It’s touchless, fast, hygienic, and far more reliable than fingerprint or facial recognition, with TCL claiming 99.9999% accuracy and performance unaffected by moisture or dirt.
