QR Code + RFID Bluetooth Access Controller, TCP/IP & Wiegand: overview
The BL-120 packs a QR code scanner, a dual-frequency card reader and Bluetooth 5.0 into an 86 × 86 mm square faceplate made for standard 86-type back boxes. It can release a door by itself through its onboard relay, or sit in front of an existing controller and pass credentials on as Wiegand 34. Typical sites are residential communities, visitor desks, hotels and unstaffed retail, where one device has to accept phone codes, cards and app entry at the same door.
Behind the tempered-glass lens, the scanner reads dynamic QR codes shown on a phone and tolerates 360° rotation, ±65° tilt and ±60° skew, so users do not have to line the screen up precisely. The RF side follows ISO/IEC 14443A at 13.56 MHz for MIFARE Classic, CPU and MIFARE DESFire cards, and also reads 125 kHz EM-type ID cards. Users are added or removed through management software.
Integration notes
Connectivity covers Wiegand (34-bit by default), RS485, USB, Ethernet TCP/IP and Bluetooth. A 10-position screw terminal block on the rear body carries 12 V/GND, RS485 (485+/485–), Wiegand (WG0/WG1), relay contacts (NO1/COM/NC1) and a door-contact input (MAG). Supply 9–15 V DC; current is about 80 mA at standby and up to 200 mA in operation. The enclosure is IP55 with 4 kV contact / 8 kV air ESD protection and runs from –20 to +60 °C. Dynamic QR codes are generated by the phone app or platform the controller is paired with, so confirm that platform for your region before a project order.

BL-120 FAQ
Can it work with my existing access control panel?
Yes. It outputs Wiegand (34-bit by default), so a panel with a Wiegand reader input treats it as a reader. RS485 and TCP/IP are also available for integration.
Which QR codes does it accept?
It is designed for dynamic QR codes displayed on a phone, generated by the app or platform paired with the controller. Codes read at any rotation, up to ±65° tilt and ±60° skew.
Does it fit a standard wall box?
The faceplate is 86 × 86 mm and the rear body is 50 mm deep, designed for an 86-type single-gang back box. Check back-box depth before installing.
Which card types can I use?
13.56 MHz ISO/IEC 14443A cards such as MIFARE Classic, CPU smart cards and MIFARE DESFire, plus 125 kHz EM-type ID cards and fobs.
Is it rated for outdoor use?
It is IP55 and operates from –20 to +60 °C, so it suits sheltered exterior doors. Avoid positions with direct driving rain.
