Introduction

On event day, check-in agents validate admission by scanning QR codes from attendee My Tix tickets. When a QR code will not scan or an attendee is not found, agents and Sub-Admins can use manual check-in to look up the guest by name or email.

Objectives

After reading this article, you will be able to:

  • Scan tickets with the Trepy check-in tool
  • Confirm valid entry and handle duplicate scans
  • Check in an attendee manually when QR scanning fails

Step 3: Manual check-in when QR scanning fails

Use manual check-in when the attendee cannot display a QR code or the scanner returns attendee not found.

  2. Search by attendee name, email, or order confirmation.
  3. Select the correct ticket from the results.
  4. Tap Check in and confirm admission.

Step 4: Escalate unresolved tickets

If you cannot find the ticket:

  1. Ask the attendee to refresh My Tix or sign in with the account used at checkout.
  2. Direct them to missing tickets troubleshooting if payment succeeded but no ticket appears.
  3. Contact the on-site Sub-Admin for override decisions.
