Zero-Fraud Check-In

Instantly Stop Ticket Sharing and Fraud

Each attendee receives a unique one-time QR ticket. The moment your staff scans it at the gate, our system marks it used. If someone tries to share a screenshot, the screen turns red. You protect your ticket revenue without arguing at the door.

No Guest App to Install

Guests scan with their native phone camera—no downloads, no accounts, no friction. Gate crew validate tickets inside any mobile browser.

Stop Code Sharing in 100ms

Each pass changes from valid to used instantly. If someone tries to scan a photocopied ticket, the gate screen flashes a bright red warning.

Zero Staff Training Required

The scanning screen shows a massive green 'VALID' or red 'USED' box. Your volunteers can start running the gate within 30 seconds of picking up a phone.

One Scan per Ticket

Create thousands of unique single-use passes in seconds. Because each code contains a cryptographically secure token, no one can guess or fake a ticket.

How One-Time QR Check-In Works at Your Event

Upload Your Guest CSV

Drag and drop your spreadsheet or connect your online registration forms.

2

Generate One-Time Passes

We generate a unique, secure QR code for every person on your list.

3

Scan at the Entrance

Your team scans tickets with any mobile camera—no custom hardware needed.

4

Pass Deactivates Instantly

The ticket goes from valid to used in 100 milliseconds, blocking duplicate entries.

What Your QR Pass Status Means at Every Scan

We handle pass validation on our servers. Your gate staff see an undeniable color-coded status, eliminating guesswork and awkward arguments.

Not Active Yet

Scanned before doors open

The pass is authentic, but your event window hasn't started yet. The ticket remains unburned. The guest can still scan in once doors officially open.

Valid Ticket

First scan at the entrance

Our system confirms the TICKET IS VALID, checks the guest in, and burns the code in 100ms. The guest walks right in.

Already Used

Duplicate entry attempt

Someone scanned this code earlier. The scanner flashes TICKET USED and blocks entry. This stops screenshots, shared texts, and duplicates instantly.

One-Time QR Codes for Event Check-In — Common Questions

Are one-time scan QR codes safe to use for event check-ins?
Yes. They are much safer than standard QR codes. Each attendee gets a unique code that deactivates permanently after the first gate scan. Screenshots, forwarded images, and duplicates fail on the spot. We enforce this on our servers, so the deactivation is instant and cannot be bypassed.
How do one-time QR codes work for secure event access?
Every code contains a secure token. When your gate staff scans it, our servers validate the token and mark it as used within 100 milliseconds. Any subsequent scan of that same code warns staff that the pass has already been used. The scanner runs in any mobile browser, meaning staff don't need to install custom apps.
What applications support one-time QR code generation for event tickets?
QRTRAC runs the entire workflow. You upload your attendee spreadsheet, generate unique one-time QR passes, and print or email them to guests. At the gate, your team scans the codes and enters your event password to validate them. Guests scan using their native phone camera with zero downloads.
Can attendees use a screenshot of their QR code to enter?
No. Once a ticket is scanned and validated, our server burns that token permanently. A screenshot of the same QR code will return an 'Already Used' error immediately, preventing the second person from entering.

What is the difference between event registration and an event pass?
Event registration covers the sign-up flow—gathering guest details and confirming attendance. An event pass is the actual ticket containing the one-time QR code scanned at the door. QRTRAC manages both. This page details the registration flow, while our Event Passes QR Code page focuses on VIP and staff credentials.
