This keyring is equipped with both a BLE Beacon and an NFC Tag. The Beacon offers standard BLE 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.

We recommend using this product with the BLE/Wi-Fi Beacon Gateway.
