RFID & QR Code Access Control Reader – Wiegand USB RS232 RS485
LIHTNE R35C/D – Smart RFID & Barcode Access Control Reader
The LIHTNE R35C/D is a next-generation dual-mode smart card and barcode reader that combines RFID card reading with 2D QR code and standard barcode scanning into one compact, wall-mount device. Designed to the universal 86mm × 86mm industry-standard form factor, it integrates seamlessly into office buildings, gated communities, scenic attractions, administrative centers, visitor management systems, smart gates, and smart home setups — giving any access control installation a powerful, flexible upgrade.
With multi-protocol communication support (Wiegand, USB, RS232, RS485, and TTL) and broad OS compatibility (Windows XP/7/8/10 and Linux), the R35C/D slots into virtually any existing infrastructure without additional middleware.
Key Features
- Dual-Mode Reading: Reads both RFID cards (125 kHz EM & 13.56 MHz ISO14443A MIFARE) and 2D/1D barcodes (QR codes and standard barcodes) in a single unit.
- Fast & Accurate: Reading speed under 200 ms with image decoding and auto-sensing for hands-free, touchless operation.
- Multi-Protocol Output: Supports Wiegand, USB, RS232, RS485, and TTL — compatible with virtually all access control panels and gate controllers.
- Wide Read Range: RFID cards readable at 3–6 cm; QR codes readable at up to 20 cm distance.
- Auto-Sensing & Buzzer Feedback: Automatically triggers on approach; audible buzzer confirms each successful read.
- Visual Indicators: Red working light, green feedback light, and green network light for instant status monitoring.
- Durable Construction: PC housing with tempered glass scanning window; operates in temperatures from -20°C to 70°C and humidity from 10%–90%.
- Standard 86-Box Form Factor: 86 × 86 × 42 mm — fits standard electrical wall boxes for a clean, professional installation.
- CE Certified: Meets CE compliance standards.
- Easy Factory Reset: Insert a pointed object into the rear Reset hole to restore factory settings and restart the device.

Frequently Asked Questions
Q: What RFID card formats does the LIHTNE R35C/D access control reader support?
A: The R35C/D supports two RFID frequencies: 125 kHz EM cards (commonly used in older access control systems) and 13.56 MHz ISO14443A MIFARE cards (used in modern smart card systems). Both formats are read at a distance of 3–6 cm for reliable, contactless access control.
Q: Which communication protocols does this QR code and RFID reader support?
A: The reader supports Wiegand, USB, RS232, RS485, and TTL output protocols. This broad multi-protocol compatibility means it integrates with virtually any existing access control panel, gate controller, or visitor management system without requiring additional converters or adapters.
Q: Is the R35C/D easy to install on a standard wall box?
A: Yes. The unit is designed to the universal 86 mm × 86 mm industry-standard form factor, which fits directly into standard 86-box electrical wall boxes. This makes installation straightforward for both new installations and upgrades to existing systems.
Q: What operating systems are compatible with this access control reader?
A: The LIHTNE R35C/D is compatible with Windows XP, Windows 7, Windows 8, Windows 10, and Linux operating systems, covering the vast majority of access control and visitor management software platforms in use today.
Q: How do I reset the device to factory settings?
A: To restore factory settings, use a pointed object (such as a pin or paperclip) to press and hold the Reset button located in the small hole on the back of the device. The reader will automatically restart and return to its default configuration.
