QRGun

QRGun is an offline QR access control app designed to validate pre-issued QR codes quickly and reliably without an internet connection. The QRGun reader uses the device camera to read codes, checks them against a local database and maintains an on-device log of every scan, making it suitable for events, venues, training sessions, residential complexes and other private facilities that operate with pre-loaded attendee lists.

Key Features

QRGun performs fast camera-based QR scanning optimized for offline validation and works entirely from a local database. It validates attendees and authorized users against stored lists, records each scan locally in a searchable log and can export scan data as Excel-format reports for post-event analysis.

Advantages

The app offers a simple operator interface that reduces training time and does not depend on internet connectivity, which is useful in locations with poor service. Keeping a local audit trail supports accountability and reporting, and the offline design is intended for teams that prefer or require on-device processing.

Limitations

This build is intended for use with pre-loaded code lists and does not perform live online checks or cloud synchronization. The reader is limited to QR scanning with the device camera and does not store images or video; online migration or cloud-synced workflows are handled separately by the developer's other services.

Development Team
