The Aqara NFC card is based on Near Field Communication, which differs from most other keycards in the market based on radio frequency identification (RFID). NFC gives you better security and higher encryption standards, and cannot be duplicated. Each Aqara NFC card has a built-in EAL5+ security chip to ensure the card's encryption codes!
Pairing the card to your lock is easy – just do it in your app in 5 seconds. Lost a key? Removing a paired card is equally simple!
