Modernizing Visitor Access with Seamless, Secure & Scalable Technology
At DEIENAMI, we partnered with a forward-looking organization to transform their traditional visitor check-in and gate pass process into a digitally streamlined, secure, and scalable system. This project was developed to cater to the diverse access control needs of offices, industrial facilities, residential complexes, and institutional campuses, ensuring a balance between high security and effortless user experience.
🔍 The Problem
Most facilities still rely on manual logs, ID registers, or outdated systems that:
- Delay the check-in process
- Compromise security due to poor visitor verification
- Lack visibility into visitor traffic across locations
- Cannot scale across multi-site operations
- Offer no digital audit trails or real-time tracking
The client wanted a centralized solution that could handle both pre-registered and walk-in visitors, automate the verification process, and support advanced gate pass issuance while integrating into their existing security infrastructure.
💡 The Solution
We designed and built a Visitor Management & Digital Gate Pass System that provides a comprehensive solution to modernize front-desk operations and security at entry points. The system supports:
- Pre-Registration & Approvals (via web/mobile)
- Instant QR-based Gate Passes
- Photo & ID Capture for Walk-ins
- Facial Recognition & OTP-based Check-ins
- Multi-Location Admin Dashboard
- Blacklist Management & Visitor Risk Tagging
- Host Notifications (SMS/Email/App Push)
- Visitor Analytics & Reporting
