Waymark Technical FAQ
Hardware & Connectivity
Q: How does the tag communicate with the Locations API without Wi-Fi? A: Waymark utilizes a multi-mode connectivity approach. It features a low-energy GPS/Bluetooth module that syncs data via the traveler's smartphone app (acting as a gateway). In major transit hubs, it can also interact with authorized Bluetooth Low Energy (BLE) beacons to log "transit events" directly to the API via the hub's infrastructure.
Q: Does the E-ink display require power to maintain the image? A: No. E-ink technology is bi-stable, meaning it only consumes power when the state of a pixel changes (e.g., updating a hotel address). Once the image is set, it will remain visible indefinitely, even if the battery were to be removed.
Q: What is the precision of the GPS module? A: The GPS module provides accuracy within 2.5 meters in open-sky conditions. For indoor tracking (airports/warehouses), Waymark transitions to BLE proximity sensing to identify specific "Gate" or "Zone" locations stored in your database.
API & Integration
Q: How do I trigger an E-ink refresh via the API? A: You call the POST /locations/display endpoint. Once the request is received, the Waymark cloud sends a push notification to the associated mobile device, which then updates the tag via a Bluetooth handshake.
Q: What is the "Verifiable Breadcrumb Trail"? A: Every time a tag pings the POST /api/locations endpoint, the event is cryptographically signed. This creates an immutable log (ledger) of every transit hub the bag has entered, preventing "spoofing" of luggage location data for insurance or enterprise compliance.
Q: Can we integrate our own private "Recovery Hubs" into the search? A: Yes. Enterprise clients can use our Location Management API to upload custom coordinates for private offices, warehouses, or partner courier sites. These will then appear in the GET /locations/search results for your specific fleet of tags.
Privacy & Security
Q: How is the data on the tag encrypted? A: All communication between the Tag, the App, and the API is encrypted using AES-256. Furthermore, the E-ink display does not store personal data locally; it only renders the bitmap sent by the authenticated API.
Q: How does "Privacy Mode" work technically? A: You can define "Geo-Fences" via the API. When the tag's coordinates are outside of a "Public Transit Zone" (like an airport), the API sends a command to clear sensitive text from the screen or replace it with a generic "Property of [Company Name]" message.
Enterprise & Logistics
Q: What is the API rate limit for bulk management? A: Our Enterprise Global plan allows for unlimited tags with a burst rate of 5,000 requests per minute, specifically designed for high-volume scenarios like a tour group of 500 people checking into a hotel simultaneously.
Q: Can Waymark be used for air cargo tracking? A: Yes. Waymark is compliant with FAA and EASA regulations regarding low-power transmitters. The GPS/Bluetooth modules enter "Flight Mode" automatically based on accelerometer data and pressure sensors, then re-sync upon landing.
