Flow: Stadium Entry Validation

Actor

Gate operator + Fan

Preconditions

• Fan has valid digital ticket in HNS app or digital wallet
• Access control system loaded with pre-game barcode export of valid tickets
• Gate device/scanner operational with loaded ticket database

Pre-Game Setup (Access Control Operator)

• HNS admin exports barcode/QR code list of all valid tickets for the match via Admin Portal
• (See Match Management (Admin) - A3: Export Access Control Data for detailed export process)
• Access control operators load the export into their offline validation system right before the game

Flow Steps

1. Approach Gate

   • Fan opens HNS app or Wallet pass with QR visible
   • App supports screen rotation, auto screen brightness to max

2. Scan Ticket

   • Gate operator scans QR code using access control device
   • Access control system validates against pre-loaded ticket database (offline)

3. Offline Validation

   • Access control system verifies QR code against loaded export
   • Checks: ticket exists in database, correct match/event, not already marked as used in local system

4. Decision & Feedback

   • If VALID: Green indicator + short beep; turnstile unlocks; access control marks ticket as USED locally
   • If INVALID: Red indicator + error message shown to operator (not found, already used, etc.)

5. Post-Game Data Sync

   • Access control operators export usage data after match
   • Data sent to HNS admin for attendance import and loyalty point calculation
   • See Match Management (Admin) - A5: Post-Match Attendance Import for detailed import process

Error/Invalid Cases

• Already Used: "Ticket already scanned at 18:42 Gate 3" (based on local access control records)
• Not Found: "Ticket not in database for this match" (not in pre-loaded export)
• Wrong Event: "Not valid for this match"
• Ticket Not Loaded: May occur if ticket was purchased/updated after export was generated

Alternative Flows

A1: Ticket Not in Pre-Loaded Database

• This scenario should be rare since export includes extra codes for post-export changes (see Match Management - A3: Export Access Control Data)
• If it occurs gate operator directs fan to customer support booth at stadium

A2: Device/App Issues

• Fan cannot open app (battery low, technical issue)
• If policy allows, use printed backup QR
• Assist at Support Desk for identity verification with OIB check

A3: Access Control System Malfunction

• If access control system completely fails during match
• Fallback to manual ticket checking with physical records
• Manual log maintained for post-game data entry into HNS system
• When closing match, admin selects "No attendance data available" (see Match Management - A5: Close Match)
