"Most smart locks on the market rely on fingerprint sensors, keypads, or companion apps. TCL, however, believes palm vein scanning is a safer, more reliable option. By holding your hand in front of the lock, the D2 Pro maps the unique vein pattern beneath your skin and verifies your identity. Unlike fingerprints, which can sometimes fail due to moisture, dirt, or wear, vein scanning is contactless and unaffected by external conditions."
"The TCL D2 Pro doesn't just focus on tech; it looks the part, too. With a sleek black-and-silver finish, the lock has a modern yet premium aesthetic that fits well on most doors. The front panel features a numeric PIN pad, the palm vein scanner, and a traditional keyhole for backup. On the interior side, you'll find a thumb latch for manual locking and a discreet battery compartment."
The TCL D2 Pro uses palm vein recognition to map unique vein patterns beneath the skin for contactless identity verification. Palm scanning is less affected by moisture, dirt, or wear than fingerprints, improving reliability for wet, sweaty, or messy hands. The lock combines a sleek black-and-silver exterior with a numeric PIN pad, palm scanner, and traditional keyhole, plus an interior thumb latch and battery compartment. Integration with the TCL Home app enables access-code management, activity logs, and auto-lock settings. Compatibility with Google Home and Amazon Alexa allows voice control and status checks.
