ScanQueue creates virtual queues using QR codes. Guests scan the code at a venue, join the line instantly, and monitor their position from any phone without installing an app. When a spot opens, notifications are sent via WhatsApp, SMS or browser push, reducing no‑shows. Staff manage the queue from a live dashboard or mobile app and can view analytics on wait times and attendance. Real‑time capacity tracking records entries and exits for venues with limits. Setup requires printing the QR code and takes only a few minutes.
