TCL has launched the D2 Pro smart lock, which utilizes infrared palm vein scanning technology to provide secure, touchless home entry for users at a price point of $189.

Key Points

• The D2 Pro uses infrared light to scan unique palm vein patterns, offering a more secure alternative to traditional fingerprint or PIN-based smart locks.
• The device features a 0.3-second recognition speed and includes on-device AI that improves accuracy over time without requiring cloud storage or subscriptions.
• Hardware includes an IP55-rated aerospace-grade aluminum body, a 10,000 mAh rechargeable battery lasting up to eight months, and BHMA Grade 3 structural certification.
• Users can manage access for multiple household members via the TCL Home app, which supports real-time notifications and remote permission settings.
• The lock is Matter-compatible, allowing integration with Apple Home, Amazon Alexa, and Google Assistant without the need for a dedicated hub.
• Backup entry methods include physical keys, key cards, and a keypad for guests or situations where biometric scanning is not preferred.

Why it Matters

This device represents a shift toward biometric security that prioritizes user convenience and privacy by keeping sensitive data stored locally on the hardware. By offering advanced palm-scanning technology at a competitive price, TCL is challenging the current market standard for smart home security and accessibility.
