<h1>Prerequisites</h1><ul class="accent-bullets"><li>INVERS Hardware:<ul class="accent-bullets"><li>Vehicles must be equipped with INVERS CloudBoxx hardware.</li><li>For RFID features, integrated card readers (windshield and/or glove compartment) are required.</li></ul></li><li>Wunder Mobility Integration:<ul class="accent-bullets"><li>The integration must be activated by Wunder Mobility.</li><li>You cannot activate or configure the technical integration yourself.</li></ul></li><li>Request via Customer Success:<ul class="accent-bullets"><li>Setup, configuration, and feature enablement (e.g., Bluetooth, RFID) must be coordinated through your Customer Success Manager (CSM).</li></ul></li></ul><hr><h1>How It Works</h1>The Wunder Mobility platform integrates with INVERS CloudBoxx to provide a robust operating system for car sharing. The CloudBoxx communicates with the INVERS server via LTE-M networks , while the Wunder Mobility Backend triggers commands and interprets vehicle events.This integration supports three primary modes of interaction:<ol class="steps-list"><li>Over-the-Air (OTA) Commands: Standard lock, unlock, and immobilize commands sent via the internet.</li><li>Bluetooth (Offline Control): Direct phone-to-vehicle communication when internet connectivity is poor or absent.</li><li>RFID &amp; Physical Hardware: Support for external access cards, internal fuel/charging cards, and physical key tracking.</li></ol><img src="https://uploads.productlane.com/70ecd8b97f0960d2bdcc3b419012fc13.png" data-processed-src="https://uploads.productlane.com/b29d66a51865c2f9958517fdf05d5847.jpeg" data-original-src="https://uploads.productlane.com/70ecd8b97f0960d2bdcc3b419012fc13.png"><hr><h1>Bluetooth Capabilities</h1>Bluetooth functionality allows fleet operators to bypass the necessity of an internet connection to control a vehicle during a rental. This is critical for vehicles parked in underground garages or countryside areas with poor reception.<h2>Offline Security &amp; Reliability</h2><ul class="accent-bullets"><li>Seamless Offline Access: The app securely synchronizes digital keys when the user has an internet connection (typically upon booking assignment). This ensures the vehicle can be accessed immediately, even if the phone loses signal in a garage.</li><li>Intent Recognition: The system is designed to distinguish between "parking" (temporarily locking) and "ending a rental" even without an active internet connection, ensuring accurate rental data once connectivity is restored.</li><li>Automatic Security: Digital keys are time-limited and purpose-bound. For enhanced security, the app automatically invalidates these keys on the device immediately after a rental is ended to prevent unauthorized re-entry.</li></ul><h2>App Modes</h2>You can configure how the app handles Bluetooth via your CSM:<ul class="accent-bullets"><li>SUPPORTED: The app attempts Bluetooth for park/drive commands but falls back to the API (internet) if Bluetooth fails.</li><li>MANDATORY: The app forces Bluetooth usage for park/drive and lock/unlock actions.</li><li>OFFLINE: Bluetooth is used exclusively via the specific offline screen.</li></ul><hr><h1>RFID &amp; In-Car Hardware</h1>The INVERS integration supports specific hardware components to manage physical access and vehicle keys.<h2>1. Customer Identity Card (Windshield Reader)</h2>This external reader allows customers to access or lock the vehicle without a smartphone. It is typically mounted on the windshield.<ul class="accent-bullets"><li>Access &amp; Identification: Users hold their assigned RFID card to the reader to authenticate. The system identifies the user and triggers the appropriate action (start booking or end rental).</li><li>Visual Feedback: The reader’s LED blinks orange during detection and changes color (green/red) to confirm the action.</li></ul><h2>2. In-Car Card Reader (Glove Compartment)</h2>This internal reader manages auxiliary cards required for the vehicle's operation.<ul class="accent-bullets"><li>Card Management: The glove compartment reader can hold up to two cards simultaneously.</li><li>Use Cases: Primarily used for fuel cards or charging cards. This ensures the system can detect if the fuel card is present before allowing a user to end a rental, preventing theft or loss.</li></ul><h2>3. Key Fob</h2>The integration supports a physical key fob holder within the vehicle.<ul class="accent-bullets"><li>Key Tracking: The system detects if the physical vehicle key is inserted into the fob holder.</li><li>Rental Logic: You can configure rental rules based on the key's presence (e.g., preventing the rental from ending if the key is not returned to the fob).</li></ul><hr><h1>Future Roadmap (Informational)</h1>Wunder Mobility is actively developing deeper integrations with INVERS for release starting in 2026. Upcoming features include:<ul class="accent-bullets"><li>Damage Detection: Automated reporting of new vehicle damage.</li><li>Smoke Detection: Alerts for potential fire hazards or smoking within the vehicle.</li><li>Driving Behavior: Telematics data regarding harsh braking, acceleration, and cornering.</li></ul><hr><h1>Step-by-Step Guide (Operator Perspective)</h1><blockquote>All technical configuration is handled by Wunder Mobility. These are the steps you follow as an operator to manage the feature in the Backoffice.</blockquote><h2>Enabling INVERS Integration</h2><ol class="steps-list"><li>Contact your Customer Success Manager (CSM) Request the activation of INVERS integration and specify which hardware modules you utilize (Bluetooth, Windshield RFID, Glovebox Reader, Key Fob).</li><li>Define Bluetooth Strategy Decide if Bluetooth should be a fallback (SUPPORTED) or the primary method (MANDATORY) for your fleet.</li><li>Configure Offline Screen Work with your CSM to enable the offline screen in your white-label app to ensure users can access controls without internet.</li></ol><h2>Managing RFID Cards (Windshield Access)</h2><ol class="steps-list"><li>Open the Backoffice Navigate to the user management view in your Wunder Mobility Backoffice.</li><li>Assign a Card<ul class="accent-bullets"><li>Search for the specific user.</li><li>In the user detail view, locate the Customer Identity Card dropdown.</li><li>Select an available (Unassigned/New) card from the list to link it to the user.</li></ul></li><li>Unassign a Card<ul class="accent-bullets"><li>Navigate to the user's details.</li><li>Click "Remove" on the assigned card.</li><li>Select a reason: <code class="inline-code-shadow bg-gray-100 border border-gray-200/60 dark:border-gray-800 font-medium dark:bg-gray-700/60 text-gray-700 dark:text-gray-200 font-mono text-md px-1 py-0.5 rounded-[0.2rem] [&amp;::before]:content-none [&amp;::after]:content-none">Unassigned</code> (makes card reusable), <code class="inline-code-shadow bg-gray-100 border border-gray-200/60 dark:border-gray-800 font-medium dark:bg-gray-700/60 text-gray-700 dark:text-gray-200 font-mono text-md px-1 py-0.5 rounded-[0.2rem] [&amp;::before]:content-none [&amp;::after]:content-none">Lost</code>, or <code class="inline-code-shadow bg-gray-100 border border-gray-200/60 dark:border-gray-800 font-medium dark:bg-gray-700/60 text-gray-700 dark:text-gray-200 font-mono text-md px-1 py-0.5 rounded-[0.2rem] [&amp;::before]:content-none [&amp;::after]:content-none">Broken</code> (removes card from pool).</li></ul></li></ol><hr><h1>Tips and Best Practices</h1><ul class="accent-bullets"><li>Bluetooth for Garages Always recommend Bluetooth-enabled vehicles for operations in city centers with underground parking. LTE-M (car) often has better reach than standard LTE (phone), but Bluetooth covers the gap when both fail.</li><li>RFID LED Feedback Users should receive visual confirmation (blinking orange/green) when scanning their card.</li><li>Managing "Ghost" Unlocks In rare Bluetooth cases, if a user ends a rental while offline, the app deletes the digital key immediately for security. However, the backend may take a few seconds to process the end of the rental. Users should be educated to wait for the vehicle to lock physically before leaving.</li><li>Card Inventory Cards in <code class="inline-code-shadow bg-gray-100 border border-gray-200/60 dark:border-gray-800 font-medium dark:bg-gray-700/60 text-gray-700 dark:text-gray-200 font-mono text-md px-1 py-0.5 rounded-[0.2rem] [&amp;::before]:content-none [&amp;::after]:content-none">LOST</code> or <code class="inline-code-shadow bg-gray-100 border border-gray-200/60 dark:border-gray-800 font-medium dark:bg-gray-700/60 text-gray-700 dark:text-gray-200 font-mono text-md px-1 py-0.5 rounded-[0.2rem] [&amp;::before]:content-none [&amp;::after]:content-none">BROKEN</code> states are permanently removed from the assignable pool.
