QR Code RFID Reader 125kHz 13.56MHz USB Wiegand Access Scanner
QR Code RFID Reader 125kHz 13.56MHz USB Wiegand Access Scanner
2-in-1 QR Code & RFID Access Card Reader — Fast, Versatile & Easy to Integrate
The Asia-Teco R35 series is an intelligent, all-in-one access card reader that combines QR code / 2D barcode scanning with RFID card reading (125 kHz EM or 13.56 MHz Mifare) in a single compact unit. With a reading speed under 200 ms, auto-induction triggering, and support for five interface types — Wiegand 26/34, RS232, RS485, TTL, and USB — it integrates seamlessly into virtually any existing access control or point-of-sale infrastructure. Made in Mainland China.

Frequently Asked Questions
Q: What RFID card frequencies does the Asia-Teco R35 QR RFID reader support?
A: The R35 series supports two RFID frequencies. The R35-ID model reads 125 kHz EM cards, while the R35-IC model reads 13.56 MHz Mifare cards. Both models also scan QR codes and 1D barcodes.
Q: Which communication interfaces does this RFID access card reader support?
A: The reader supports Wiegand 26/34, RS232, RS485, TTL, and USB, making it compatible with virtually any access control panel or POS system that has a Wiegand input or serial interface.
Q: Can this QR code RFID reader work with my existing access control system?
A: Yes. Because it supports Wiegand 26/34 output — the most widely used access control standard — it can drop-in replace most existing card readers without changing your controller. Simply wire it to your Wiegand input and configure your controller for the card format you are using.
Q: What operating systems are supported when using the USB interface?
A: The reader is compatible with Windows XP, 7, 8, and 10 as well as Linux. It operates as a standard USB HID device, so no custom driver is required in most setups.
Q: What is the QR code scanning range of this reader?
A: QR codes and 2D/1D barcodes can be read at distances of 0–20 cm from the scanner lens. RFID card reading range is 3–6 cm. The 45° slanted camera angle makes it easy for users to present codes naturally without precise alignment.
