Overview
Not a fingerprint lock, this TCL deadbolt reads the vein pattern beneath the palm, so worn prints and children's fingers are less of a problem. Wi-Fi links it to the TCL Home app and voice assistants, and a rechargeable pack powers it.
Palm vein reading works with wet hands or arms full of groceries, and the six entry methods cover every family member. Spec details are thin beyond the bullets, with no weight, dimensions or warranty, and the doorbell appears only in the title.
Who it's for
Busy families, property managers and hosts who want contactless entry plus codes for cleaners and sitters will use its range of options. Anyone who needs a lock with a stated warranty should keep looking.
Pros and cons
- Palm vein works with wet hands
- Six ways to unlock
- Rechargeable with USB-C emergency port
- Guest codes from the TCL Home app
- Warranty, weight and dimensions not listed

Performance notes
Recognition scans vascular patterns under the skin, which the listing says avoids failures from worn prints, wet hands and bright sunlight. The auto-lock timer secures the door after it closes. Runtime per charge depends on use, and a low-power alert plus the USB-C port guard against lockouts.
