Aqara AL-D02D contactless proximity smart card in Blueberry color is an active NFC access card designed for short-range contactless communication. Intended primarily for use with Aqara Smart Lock U200 and other NFC-enabled access control systems, the card provides tap-to-read convenience for unlocking doors, identifying users and exchanging small amounts of data. The card supports secure assignment to a single smart lock for controlled access and works as part of a smart home or office environment that includes Matter over Thread and common platforms such as Apple Home, Google Home, Alexa, SmartThings and Aqara Home.

Programming and assigning access to the card is performed via inductive NFC communication, making setup quick and straightforward. Its active, contactless design enables fast, intuitive door unlocking with a simple tap near the reader, and its compact card form factor is convenient for daily carry.
