Check Work is a complete employee attendance tracking system combining QR code check-in, GPS geofencing, and AI-powered face recognition with liveness detection to prevent buddy-punching.

Built with Node.js, Express, and better-sqlite3, the system works both online and offline, automatically syncing records once connection returns. It includes automated worked-hours calculation, timesheet generation, and Excel export.

The package includes a ready-made Android app (APK) using a WebView wrapper, a full admin panel with self-service password management, and an 11-language interface (Russian, Kazakh, English, German, Spanish, Turkish, Hebrew, Chinese, Japanese, French, Dutch).

Detailed step-by-step installation documentation is included in both Russian and English, making this accessible even for buyers with limited technical experience. The system is designed to be self-hosted, giving businesses full ownership of their data without recurring subscription fees.

Ideal for small and medium businesses, offices, retail locations, or warehouses that need a reliable, fraud-resistant attendance solution without paying per-employee monthly fees.
