What happens if two people scan the exact same pass at different gates simultaneously?

URPASS utilizes atomic PostgreSQL database locks. Exactly one scan will be recorded as successful, and the other will immediately flash red with an 'Already Checked In' duplicate warning.

Do volunteers need to install an app on their phones?

No. Volunteers simply open a web link in Safari or Chrome, enter your 6-digit gate PIN, and begin scanning immediately using their phone's camera.

Can we see which gate admitted each attendee?

Yes. Every check-in log records the exact gate ID, device identifier, volunteer name, and millisecond timestamp.

Is there a limit on how many phones can scan simultaneously?

No. You can connect 2, 10, or 50+ volunteer phones concurrently without hitting licensing caps or performance throttling.

How Does URPASS Synchronize Multiple Event Gates?

URPASS uses an atomic PostgreSQL cloud database with row-level transaction locks to synchronize check-in events across multiple gates in real time. Volunteers open a PIN-secured scanner link on standard smartphones. When a pass is scanned at Gate A, it locks instantaneously across the entire network in under 0.3s, guaranteeing that the same pass or a forwarded screenshot cannot be used simultaneously at Gate B.

✓Unlimited concurrent entrance lanes and volunteer devices across multiple gates

✓Atomic transaction locks prevent simultaneous duplicate check-in race conditions across gates

✓Zero app downloads: volunteers open secure PIN links directly in mobile Safari or Chrome

✓Real-time gate telemetry showing arrival breakdown across North, South, and VIP entrances

FEATURES

Everything you need

Unlimited Simultaneous Lanes

Deploy as many scanning lanes as your venue requires. Coordinate North, South, East, and VIP gates in real time.

Atomic Duplicate Lockout

If an attendee attempts to share a ticket screenshot with a friend at another gate, the second scan triggers an immediate red alarm.

Zero App Download for Staff

Volunteers access the camera scanner via a secure event PIN in Safari or Chrome, preserving device storage and battery.

Sub-0.3s Scan Verification

Fast optical decoders verify passes instantly with audible success chimes and haptics, even in noisy outdoor entrance areas.

Secure Volunteer PIN Access

Keep financial reports and attendee contact databases private while giving gate staff pure scanning functionality.

Per-Gate Live Analytics

Track arrival velocity and queue bottlenecks per gate to redeploy volunteers dynamically to the busiest entrance.
