Trend of contactless palm unlocking? TCL D2 Pro is now part of it! It recognizes your veins and lasts up to 10 months

Biometrics are increasingly popular and widespread in smart locks. The **TCL D2 Pro** Palm Vein Smart Lock scans the vein pattern directly from your palm instead of the usual fingerprints or face; according to the manufacturer, the **AI system** in the lock can react to your palm in one second. The device’s algorithms also learn and continuously adapt to changes over time, so reliability should remain high even after years of use.

A positive point for users who value privacy is definitely the fact that all palm templates are stored locally inside the lock, not in the cloud. The device also houses a **10,000mAh battery**, which is said to last up to 300 days of operation, or roughly 10 months.

The lock charges** via USB-C**. Wireless charging would probably fit the overall futuristic concept of the lock, but unfortunately, it is missing.

TCL D2 Pro also offers other unlocking methods

With the TCL D2 Pro lock, you don’t necessarily have to rely solely on veins, although it is its primary feature. It also supports remote unlocking via the TCL Home app or voice commands through various assistants like Google Assistant. It is also compatible with NFC chips.

For touch unlocking, it offers a four to eight-digit **PIN or a mechanical key**, just in case. The model is made of a metal body and has a built-in alarm in case of attempted forced entry.

It is currently available on the official website of TCL, priced at 160.65 dollars with a current 15% discount. Converted, the price is approximately **3,370 CZK**.
