QRGun

QRGun is a compact offline access-control reader that validates pre-issued QR codes quickly and without an internet connection. The app uses the device camera to scan codes, compares them to a locally stored list, records each scan on the device, and can export attendance or access reports in Excel format. Event organizers, venue staff, property managers and other operators will find QRGun useful when connectivity is limited or when a simple, privacy-focused validation tool is preferred, since it does not save photos or videos and operates entirely from a local database.
