This keyring is equipped with both a Bluetooth® Low Energy Beacon and an NFC Tag. The Beacon offers standard Bluetooth® Low Energy tracking features and, in addition, the payload also contains the battery charge level and the state of the alarm button. The NFC Tag is empty, freely programmable; it can be left rewritable or permanently locked.
