Trailhead Check-In (Proof of Concept) • Optional • No account required
Trailhead ID:CA-LA-EM-001
Trail Overview
Scan-to-check-in helps reduce uncertainty if someone becomes overdue. Personal data should be retained only
for a limited time and never displayed publicly.
Safety reminder: Carry water, a light, and adequate layers. If you will finish near sunset, plan for delays.
If there is limited cell coverage, consider hiking with a partner and leaving a plan with someone off-trail.
Proof-of-concept: the “weather” below uses mock data. In production, you would fetch weather from a backend
(recommended) or from a third-party API directly from the browser.
Check In
Quick, optional registration. In production, you would POST this to your API and store a check-in record.
Map (Placeholder)
For a fast proof-of-concept, embed a map link. For a richer experience, use Mapbox GL JS or MapLibre and load a GPX/GeoJSON route.
Suggested quick approach
Link to a map destination (Google/Apple) + optional embedded static image.
In production, scanning the QR again would detect an active check-in by phone/ID and present a one-tap checkout.
Recommended production approach: check-ins generate a unique check-in ID (UUID). The checkout page can look up
the active record by ID (stored client-side) and mark it closed server-side.
