The Aqara NFC Card (Model: AL-D02D) offers a secure and convenient access solution for your smart home ecosystem. Designed specifically for compatibility with the Aqara Smart Lock U200, this card allows you to open your door with a single tap. Each NFC card can be personalized to pair with a single lock, enabling you to define separate access permissions for family members, employees, or guests. Its key technical highlight is the EAL5+ financial-grade security chip, which provides advanced protection against copying and unauthorized access to the key information stored on the card. Thanks to sensitive induction technology, the card reads quickly and reliably. Its compact dimensions (50 x 30 x 3 mm) and lightweight design make it easy to carry in your wallet or keychain. In daily use, the Aqara NFC Card is ideal for situations where fast, contactless entry is important. When your hands are full or you prefer not to enter a password, simply tap the card to the lock and gain entry in seconds. It is also useful as a temporary access card for short-term rental hosts or office workers. Programming the card is straightforward via the Aqara Home app, and it integrates seamlessly with platforms such as Apple Home and Google Home.
