Exploration

1. PWA Interface Setup

  • Initial Configuration
    • Staff opens Progressive Web App
    • Enters identifying nickname for system tracking
    • Selects specific checkpoint location
    • Interface adapts to chosen checkpoint

2. Checkpoint Locations

  • Three Strategic Points
    • Checkpoint 1: Scanned when students leave the checkin auditorium
    • Checkpoint 2: Scanned when getting back on the bus from Walmart
    • Checkpoint 3: Scanned on the way into the gym (final destination)
  • Each checkpoint tracks different event phase
  • Location selection determines data context

3. Scanning Process

  • QR Code Scanning
    • Camera interface for quick scanning
    • Automatic group information retrieval
    • Manual entry option for backup
    • Immediate confirmation display
  • Validation Steps
    • Verifies group is at correct checkpoint
    • Confirms scanning staff member identity
    • Records timestamp and location

4. System Integration

  • Real-time Processing
    • Updates group status in database
    • Records checkpoint completion
    • Timestamps each interaction
    • Updates monitoring dashboard
  • Error Prevention
    • Validates correct checkpoint sequence
    • Prevents duplicate scans
    • Flags unusual patterns
