Global electronics giant TCL has introduced a new generation of smart locks under its home security division, with a bold leap forward in biometric innovation. The flagship of the new lineup, the TCL D2 Pro Palm Vein Smart Lock, leads the D2 series, which also includes the D2 Plus and standard D2 models. All three are now available for purchase worldwide through TCL’s official website and Amazon.
Palm Vein Recognition: A Sci-Fi Feature Comes to Life
The standout feature of the D2 Pro is its futuristic palm vein recognition system, allowing users to unlock their doors simply by holding a hand over a dedicated scanner. This technology reads the unique vein patterns beneath the skin, offering a high level of security and convenience.
Unlike facial or fingerprint recognition, palm vein authentication is contactless, reducing wear and tear while improving hygiene. TCL claims its offline AI system continuously learns and adapts to subtle changes in users’ palm patterns, maintaining accuracy even as people age.
Designed for Privacy and Power Efficiency
The D2 Pro is built with local data storage, ensuring user biometric data never leaves the device—avoiding common risks tied to cloud-based systems. At a price point of $169, the D2 Pro delivers not only advanced technology but also a strong focus on privacy.
The device is powered by a 10,000mAh rechargeable battery, capable of delivering up to 10 months of usage on a single charge. A USB-C port is included for fast and convenient charging. While the device lacks wireless charging support, it still stands out for its energy efficiency and long-lasting performance.
Refined Aesthetics and Versatile Access Options
The D2 Pro separates the biometric scanner from the touchscreen keypad, enhancing both aesthetics and user experience. The sleek, modern design makes it suitable for contemporary home interiors, while also improving ease of use for family members and guests.
In addition to palm vein scanning, the D2 Pro offers multiple access methods, including:
- Smartphone app control
- Voice assistant integration (Google Assistant and Amazon Alexa)
- NFC-enabled key fobs
- Traditional physical keys
This range of access options makes the D2 Pro suitable for a wide range of users—from tech-savvy homeowners to those who prefer classic methods.
Budget-Friendly Alternatives: D2 Plus and Standard D2
For users who don’t require palm recognition, TCL offers two more budget-friendly models:
- D2 Plus ($119): Replaces palm scanning with a fingerprint reader, while maintaining app, keypad, and key access.
- Standard D2 ($79): Offers basic features such as keypad entry, doorbell functionality, and key access—ideal for those seeking a simple and affordable smart lock solution.
A Step Toward the Future of Home Security
With the release of the D2 Pro and its siblings, TCL reinforces its position in the growing smart home market. The addition of AI-powered palm recognition, offline data privacy, and long battery life set a new standard for biometric security solutions.
