Tech Under the Hood: BLE, NFC, Wi‑Fi, and Matter
Most next-gen locks use Bluetooth Low Energy for quick, nearby authentication, pairing ephemeral session keys with device-bound credentials. Proper implementations leverage ECDH key exchange, rotate identifiers to reduce tracking, and verify proximity without broadcasting reusable secrets that attackers could replay.
Tech Under the Hood: BLE, NFC, Wi‑Fi, and Matter
NFC offers fast, tap-to-enter access even when Wi‑Fi is down, while offline-first designs store validated credentials safely on the lock. Time-bound codes and rolling cryptograms let you open doors during outages without exposing master keys, keeping reliability front and center.
