GSS QR Code Access Control Reader is a secure, flexible door and lift access control solution that uses QR code scanning for fast, contactless entry. Designed for offices, residential buildings, co-working spaces, hotels and visitor management, the system includes a compact QR reader, a controller with relay door I/O, and full software support (SDK & API) for integration with third-party applications and building management systems. It supports time/date validity, one-time and recurring codes, usage limits, and remote issuance revocation ideal for guests, contractors, deliveries and temporary access.
Key Features
• Contactless QR scanning for fast, hygienic access
• Controller with door relay, lock monitoring, exit button and tamper detection
• Date/time validity, expiry, and scheduled access windows
• One-time QR, multi-use QR, and recurring QR code issuance
• Limitations & quota control- set max uses per code
• Built-in real-time logging and audit trail (user, time, door, result)
• Offline mode with secure caching and automatic sync when online
• Supports encrypted QR (HOTP/TOTP or RSA signed tokens) for higher security
• SDK (Windows/Linux) and RESTful API for seamless integration with PMS, ERP, visitor systems, and custom apps
• Multi-door and multi-site management via centralized software
• Easy installation- PoE or 12/24V power options; standard Wiegand/RS485/TCP interfaces
• Optional touchscreen for on-device code generation or PIN fallback
• Role-based admin controls and configurable event notifications (email/SMS/webhook)
Technical Specs (typical)
• Reader: 2D QR DataMatrix scanner; scan distance 5–50 cm (model dependent)
• Controller: 1x relay output (lock), 1x auxiliary relay, 2x supervised inputs (door, exit), tamper switch
• Network: Ethernet (TCP/IP), optional Wi-Fi LTE module
• Power: PoE (802.3af) or 12–24 VDC
• Operating temp: −20°C to +60°C; IP54 housing (IP65 outdoor option)
• Memory: local event buffer (configurable), secure storage for offline auth
• Protocols: REST API, MQTT/Webhook support, Wiegand/RS485 for legacy readers
Integration & Developer Support
• Full SDK with sample code (C#, Java, Python) and example projects
• RESTful API endpoints for issuing, revoking, and validating QR codes; webhook event callbacks for live monitoring
• API supports token-based auth, rate limits, and scoped API keys
• Documentation, Postman collection, and technical support for system integrators
• White-label options and multi-tenant deployments supported
Benefits
• Fast, low-cost deployment for temporary and permanent access scenarios
• Eliminates physical cards for visitor and delivery workflows
• Granular control over access windows and usage limits
• Easy integration into existing security ecosystems (PMS, HR, Visitor Apps)
• Improved auditability and traceability with timestamped logs
• Scales from single-door installations to campus-level deployments
Typical Use Cases
• Visitor management (temporary check-in QR)
• Hotel / short-term rentals (mobile QR for room access)
• Corporate offices (contractor / vendor passes)
• Logistics & deliveries (time-bound delivery access)
• Lift/elevator floor access control (QR + floor mapping)
• Events & co-working spaces (ticketed/limited access)
