Frequently Asked Questions
Q: What types of credentials does this RFID QR Code access control reader support?
A: This reader supports multiple credential types including 2D QR codes (displayed on a screen or printed on paper), Mifare One IC cards, mobile phone NFC, and DESFire EV2 smart cards — making it one of the most versatile access control readers available for modern installations.
Q: How many users can be stored on this access control reader?
A: The reader supports a maximum of 20,000 users. It also supports up to 20,000 IC card and QR code bindings through its compatible app/applet, making it well-suited for large facilities and high-traffic entry points.
Q: What communication interfaces are supported for integration with existing systems?
A: This reader outputs via Standard TTL, RS485, and Wiegand 26/34 — the three most widely used protocols in professional access control systems — ensuring compatibility with a broad range of access control panels and controllers.
Q: Can this reader be used outdoors?
A: Yes. The reader comes with a dedicated shading and waterproof cover (150mm × 103mm × 80mm) designed to protect the device from rain and outdoor conditions, making it suitable for exterior door installations, parking gates, and other exposed mounting locations.
Q: What is the reading distance for QR codes and RFID cards?
A: QR codes can be read at a distance of 2–10 cm (note: 0–2 cm is the blind zone, so a minimum of 3 cm is recommended). RFID IC cards and NFC devices have a card reading distance of 3–6 cm, with a read time of under 0.3 seconds.
