Product Guide & Selection
Product Overview
The QR-code access-control terminal is a smart device launched by Vguang for IoT access-control passage scenarios. It features a 5-inch touchscreen plus QR-code / card-swipe dual-mode reading, a metal housing and Ethernet / Wi-Fi support, ideal for integrated access control and attendance in buildings, campuses and schools.
The M300 is a code-scanning device developed by Vguang for the access-control scanning field. It integrates QR-code reading and 13.56MHz RFID card (NFC) reading to deliver a combined 'scan + swipe' function. With an embedded-mount design and a compact body of only 88.30mm x 88.30mm x 28.35mm, it can be easily embedded into turnstiles and access-control panels. The product offers multiple output interfaces - USB, Wiegand, TTL, RS232 and RS485 (five output modes in total) - to meet integration needs with different access controllers and card-reading systems. It reads fast and accurately, with an average speed of about 100ms (as fast as 0.1s) and supports continuous reading. Configured via the bundled VguangConfig tool, it is easy to debug and well suited to campuses, buildings and lane turnstiles that require rapid credential verification.
Core Capabilities
Scan + Swipe in One
Integrates QR-code reading and RFID card reading (ISO 14443A/B protocol cards, physical ID-card numbers) so a single module verifies both credential types.
Multi-Interface Output
Supports five output modes - USB, Wiegand, TTL, RS232 and RS485 - compatible with most access main controllers and card-reading systems.
High-Speed, High-Precision Reading
Average read speed 100ms per scan, as fast as 0.1s; reading accuracy >=8mil, supports phone screens and printed codes.
Wide-FOV Multi-Angle Reading
Horizontal FOV 72.1 degrees, vertical 56.6 degrees, supports tilt +/-56.3 degrees, rotation +/-360 degrees, yaw +/-55.7 degrees, so users can read without precise aiming.
User-Friendly Configuration Tool
Paired with the VguangConfig tool, parameters are pushed by generating a config code that is scanned, making debugging convenient.
Clear Status Indicators
Equipped with red / green indicators, a white fill light and a buzzer, so scan status and results are clearly visible.
