Product Guide & Selection
Product Overview
The QR-code access controller is a smart device launched by Vguang for IoT access-control passage scenarios. It is an ultra-thin QR-code access-control reader head that supports mobile dynamic codes and IC cards, with Wiegand / RS485 output for easy legacy-system upgrade.
The MP (MP86 scanner) is a code-scanning device developed for the access-control field, with an IP66 ingress rating suitable for outdoor / semi-outdoor access passages. It integrates QR-code reading and 13.56MHz RFID card (NFC) reading to deliver a combined 'scan + swipe' function. It supports Wiegand and 485 output to connect directly to traditional access controllers, and also supports Ethernet output with a built-in relay module that can directly control the door (switching-signal output), removing the need for bulky access controllers and simplifying deployment. Wall-mounted with a body size of 88.8mm x 89mm x 42.95mm, an ABS + tempered-glass scan window and blue / red / green indicators with a buzzer, it reads fast and accurately - about 100ms on average (as fast as 0.1s) - and supports continuous reading.
Core Capabilities
Scan + Swipe in One
Integrates QR-code reading and RFID card reading (physical ID-card IDs, NFC phones, Mifare series, etc.) so a single terminal verifies both credential types.
Multi-Interface + Built-in Relay
Supports Wiegand, 485 and Ethernet output; the built-in relay module (DC 30V/1A) can directly output a switching signal to control the door and connect to the existing access system (either normally-open or normally-closed wiring).
IP66 Protection + Wall Mount
IP66 ingress rating, wall-mounted, suitable for outdoor / semi-outdoor access passages and turnstiles.
High-Speed, High-Precision Reading
Average read speed 100ms per scan, as fast as 0.1s; reading accuracy >=5mil (higher than the >=8mil of M300/M340/M350), supports phone-screen codes.
Wide-FOV Reading
Horizontal FOV 73 degrees, vertical 55 degrees, so users can read without precise aiming.
Status Indicator & Voice Prompt
Red / green / blue tri-color indicators + buzzer prompt make scan and swipe status clearly visible.
