The dossier system provides employers with a simple way to collect, store, and manage all necessary documentation for employees, such as passports and visas. It verifies document authenticity and generates reminders when documents like visas are about to expire. The system acts as a gateway to verify the documentary evidence required by law for employing workers and gives access to employee details, reports, security options like fingerprint biometrics, and advanced functionality for human resource management tasks. It allows for integration with other systems like payroll and has security controls, audit trails, and historical retention of personnel records.
