The BlueKey DriverID app allows your Phone to broadcast a Driver ID tag over Bluetooth, enabling a configured GPS tracker to identify the authorised ID and allow the vehcile to start by disabling the immboilizer HOW IT WORKS Traditionally, Driver ID systems required an iButton or RFID tag, which meant installing additional hardware and wiring a reader into the vehicle. The BlueKey Driver ID app replaces the physical iButton or RFID tag. The BlueKey app broadcasts a unique ID for a short number of seconds, this signal can be detected by a compatible GPS tracker, and if recognised, allow you to start the vehicle. Your Driver ID is randomly generated and stored permanently on your device — it never changes, so it always identifies you. No need to install additional RFID or iButton scanners on the vehicle tracker, simply use the phone bluetooth to transmit an ID, and the GPS tracker bluetooth will authenticate recongnised IDs and authorise vehicle starting. FEATURES • One-tap broadcast — tap the central button to start broadcasting your Driver ID instantly • Timed broadcasts — choose from 5s, 10s, 20s, 30s, 1 minute, or 2 minutes; stops automatically, and if app is closed to background. • Permanent Driver ID — your UUID, Major and Minor values never change between sessions • Share your Driver ID — send your full beacon Driver ID string to the fleet manager so they can configure the tracker to allow for vehcile starting with your authorised ID • Face ID / Touch ID lock — optionally require biometrics before each broadcast for extra security • No account required — everything is stored on-device using iOS Secure Storage • Clean, minimal design — dark UI optimised for quick use PRIVACY BlueKey does not collect, transmit, or store any personal data. Your Beacon ID never leaves your device except via the Bluetooth signal you choose to broadcast. BLUETOOTH USAGE BlueKey uses Bluetooth to broadcast your Driver ID signal. The Bluetooth permission prompt will appear the first time you tap to broadcast. You can revoke this permission at any time in iOS Settings.
