HW-1930 OEM 12V Wide Angle Anti-glare Barcode Scanner Module
Professional barcode scanner module with Wiegand RS485 interface designed for access control systems and transit gates.
Product Overview
Purpose-built for continuous operation in transit gates and secure entry points, the HW-1930 combines high-speed scanning with exceptional environmental adaptability. Its 0.3MP global shutter sensor captures QR codes from reflective mobile screens without glare interference, even under direct sunlight. A protective acrylic cover shields the optics from dust while maintaining scan clarity.
With support for USB, TTL, RS232, RS485, and Wiegand interfaces, and a wide 3.3V-16V power input, the module simplifies hardware integration across diverse platforms. Optional upgrades include a built-in 13.56MHz RFID reader for hybrid QR + card reading, as well as an OCR variant for passport and ID document MRZ recognition.
Key Advantages
- Glare-resistant imaging ensures reliable mobile barcode reading in outdoor or brightly lit environments
- Configurable interface and power options reduce design complexity
- Available with RFID or OCR functionality for multi-credential applications
- Proven 24/7 reliability—currently in service on Ho Chi Minh City's first metro line since 2023
- Optimized for turnstiles, gated entry, and access control systems where uptime is critical
