Product Guide & Selection
Product Overview
The embedded QR-code scanner is a smart device launched by Vguang for IoT access-control passage scenarios. With its self-developed image-decoding core it reads all 1D / QR code symbologies quickly; it features a flat tempered-glass panel, borderless design and is only 28.35mm thick.
The Q300 is a code-scanning device developed by Vguang for the embedded field, combining QR-code reading and RFID card reading to meet both scan and swipe application needs. It supports five output modes - USB, Wiegand, TTL, RS232 and RS485 - with great integration flexibility, making it easy to embed into various self-service terminals, lane turnstiles and access-control systems. The manual highlights its fast, accurate reading (as fast as 0.1s) and the bundled user-friendly VguangConfig tool that makes on-site debugging more convenient.
Core Capabilities
Scan / Swipe in One
Integrates QR-code reading and 13.56MHz RFID card reading to cover both payment and access-control scenarios at once.
High-Speed Reading
Read speed as fast as 0.1s, averaging 100ms per scan, and supports continuous reading.
Multi-Interface Output
Supports multiple communication modes - USB, RS232, RS485, TTL and Wiegand - to suit different hosts and upper computers.
User-Friendly Configuration
Generate a config code via VguangConfig and scan it to push parameters; settings take effect after power-off restart.
Wide Environment Adaptability
Operating temperature -20C~65C, ambient illuminance 0-100000Lux (no direct sunlight), relative humidity 5%-95%.
Status Indicator
Red / green / white indicators + buzzer give intuitive feedback on scan and swipe status.
