R35 QR Code & RFID Reader – USB Wiegand RS232 RS485 Scanner
R35 QR Code & RFID Reader – USB Wiegand RS232 RS485 Scanner
R35 2-in-1 QR Code & RFID Access Card Reader
The Asia-Teco R35 is a versatile, intelligent access card reader that combines 2D QR code / barcode scanning with RFID card reading (125kHz EM or 13.56MHz Mifare) in a single compact unit. With ultra-fast read speeds under 200ms, a high recognition rate, and broad interface compatibility — including Wiegand26/34, USB, RS232, RS485, and TTL — this reader integrates seamlessly into virtually any existing access control, visitor management, or self-service system.
Whether you're upgrading a building's entry system, managing a service hall, securing gates, or deploying smart ticketing kiosks, the R35 delivers reliable, contactless identification with minimal setup. Made in Mainland China.
Key Features
- Dual-mode identification: Reads 2D QR codes & 1D barcodes plus RFID cards (EM 125kHz or Mifare 13.56MHz) — choose the model that fits your setup.
- Lightning-fast scanning: RFID read time <200ms; QR code read range up to 20cm.
- Multi-interface support: Wiegand26/34, USB, RS232, RS485, TTL — connects to any Wiegand-compatible controller out of the box.
- Auto-induction with audible beep: Hands-free detection triggers scanning automatically with a confirmation beep.
- Wide voltage input: Operates on 4–12V DC, making it adaptable to diverse power environments.
- Durable construction: PC & tempered glass housing; rated for -20°C to 70°C and 10%–90% humidity.
- Plug-and-play OS support: Compatible with Windows XP, 7, 8, 10, and Linux — no complex driver installation required.
- LED status indicators: Red = working, Green = feedback, Light Green = network/internet connected.

Frequently Asked Questions
Q: What is the difference between the R35-ID and R35-IC models?
A: The R35-ID supports QR code / 2D barcode scanning combined with EM 125kHz RFID card reading, while the R35-IC supports QR code / 2D barcode scanning combined with Mifare 13.56MHz RFID card reading. Choose the model based on which type of RFID cards your existing access control system uses.
Q: Can the R35 QR Code RFID Reader connect to my existing Wiegand access controller?
A: Yes. The R35 is fully compatible with any standard Wiegand input controller (Wiegand26 or Wiegand34 protocols), making it a straightforward upgrade or addition to most existing access control systems without requiring a full system replacement.
Q: Does the R35 RFID reader work with mobile phone QR codes?
A: Absolutely. The R35's camera-based image decoding engine can read QR codes displayed on mobile phone screens from up to 20cm away, making it ideal for mobile coupon redemption, e-ticket validation, and contactless visitor check-in scenarios.
Q: How do I reset the R35 access card reader if it becomes unresponsive?
A: Insert a sharp object (such as a pin or paperclip) into the RESET hole located on the back of the unit. Hold it in until the device automatically restarts and returns to normal operation.
