QR event check-in apps
This cluster comprises mobile and web applications that use QR codes for event registration, ticketing, check-in, and access control, often with features like real-time validation, offline sync, and admin management. The dated history before the index start shows sporadic early entries, with just one in 2021, one in 2023, one in 2024, then a gradual rise through 2025 with small peaks in August and November, each with two entries. VIPPassScanner leads on traction with1 star, while entry-pass-web-migration and check-in trail with0 stars each.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
