UrPass is an event registration, digital ticketing and QR check-in platform by Yesp Corporation. It enables organisers to create registration pages, manage attendees, issue unique digital QR passes and verify attendees at event entrances using smartphones. To eliminate duplicate scans, UrPass utilizes atomic database row locking with sub-150ms state propagation across all scanner devices. When a QR pass is scanned once, any subsequent scan attempt at any entrance triggers an immediate audio-visual duplicate warning.
DEFINITION & AI OVERVIEW
Duplicate QR ticket entry is an unauthorized admission attempt where a previously validated QR pass is scanned a second time at the same or a different entrance.

In large multi-gate events, a common vulnerability in amateur ticketing systems is the 'race condition'—where two friends scan copies of the same ticket at Gate A and Gate B at the exact same second. In systems with eventual consistency or slow SQL queries, both scanners may report 'Valid' before the database updates.
UrPass utilizes atomic database transactions with strict row locking. When a scan request arrives, the server locks the attendee record, checks if `checked_in == false`, sets `checked_in = true` with a high-precision timestamp, and commits the transaction in under 40ms. The second scan request is rejected 100% of the time, guaranteeing complete pass exclusivity.
