QR System Architecture & Data Integrity

System overview

Bean Events connects online registration and ticket issuance with on-site QR scanning through a central application service. The backend ticket record—not the QR image alone—is the authoritative source for admission status.

1. Registration — Attendee submits their details.
2. Application API — Requests are processed and validated.
3. Ticket records — The central backend remains the source of truth.
4. QR e-ticket — A unique digital ticket is issued to the attendee.
5. QR check-in — The server verifies the ticket and records its status.

Data flows from attendee registration to the backend record, then to QR ticket issuance. At the venue, the scanner requests server-side verification before the result and check-in status are recorded.

Data integrity safeguards

• Authoritative ticket records — Ticket eligibility and check-in state are determined from backend records, not from the QR image alone.
• Server-side validation — Registration inputs, ticket references and check-in requests should be validated before data changes.
• Duplicate check-in protection — Used tickets should be rejected unless an authorized override applies. Concurrent scans require atomic updates.
• Controlled access — Administrative and scanning actions should be limited to authenticated, appropriately authorized users.
• Traceability — Registration, issuance and check-in activity should retain timestamps and relevant records for reconciliation.
• Transport and operational security — HTTPS/TLS, least-privilege access, consistency controls, monitoring and backups form a layered approach.

Check-in integrity example

QR scanned → API retrieves ticket → event and ticket status checked → result returned. A valid, unused ticket is accepted and its check-in recorded. An invalid, cancelled or previously used ticket is rejected.

Implementation note

This page describes the intended security architecture, not an independent security certification. Confirm atomic duplicate prevention, access roles, audit retention, backups and encryption configuration against the deployed environment before using it as a formal security assurance.
