The Aqara NFC card relies on near field communication, which is different from most other key cards on the market based on radio frequency identification (RFID). NFC gives you better security and higher encryption standards, and it can't be duplicated. Every Aqara NFC Card has a built-in EAL5+ security chip to ensure the card's encryption codes!
Pairing the card with the lock is easy – just do it in your app in 5 seconds. Lost key? Removing a dual card is just as simple!
