QR Code Access Controller with Touch Keypad, 13.56 MHz: overview
The QT-110 is a standalone QR code access controller for doors with a steady flow of visitors. It reads time-limited dynamic QR codes from a phone screen or paper, plus 13.56 MHz cards and phone NFC card emulation, and releases the lock through its own relay. Couriers, contractors and short-stay guests can be sent a code that expires on schedule instead of collecting a card that has to be returned.
The 120 × 80 × 22.67 mm unit has a metal frame and a glass front with backlit touch keys. Its 648 × 488 image sensor and twin fill lights scan in daylight or darkness, decoding in about 100 ms on average at 5–18 cm, with full 360° rotation and ±45° tilt accepted. Besides QR it handles Data Matrix, PDF417, UPC and the common 1D symbologies. On the RF side it takes UIDs from ISO/IEC 14443A cards (MIFARE Classic, Ultralight, DESFire EV1, NTAG and CPU cards) and ISO/IEC 15693 cards.
Integration notes
Three wiring modes share one harness. Controller mode uses the NO/COM/NC relay contacts, a door-contact input (MAG) and an exit-button input (BUT). Reader mode sends Wiegand on WD0/WD1 with BEEP and GLED control lines, so the unit can sit in front of any panel that accepts a Wiegand reader. RS485 mode uses 485A/485B. Power is 12 V DC (≤ 200 mA), or 5 V through the 1.5 m USB to Mini-USB lead (≤ 500 mA). Dynamic QR codes are issued by a management app or platform; confirm which platform is available for your region before ordering.

QT-110 FAQ
What is a dynamic QR code, and does the QT-110 read them?
A dynamic QR code is time-limited and refreshes, so an old screenshot stops working. The QT-110 reads these codes; they are generated by the management app or platform paired with the controller.
Can it act as a reader for my existing panel?
Yes. In reader mode it sends Wiegand on the green (D0) and white (D1) leads and accepts buzzer and LED control. RS485 mode is available as an alternative.
Does it read encrypted card data?
No. It reads the UID of 13.56 MHz ISO/IEC 14443A and ISO/IEC 15693 cards, including MIFARE Classic, DESFire EV1, NTAG and CPU cards.
How is it powered?
Use 12 V DC (±5%) with up to 200 mA available, or connect the supplied 1.5 m USB to Mini-USB lead, which draws up to 500 mA at 5 V.
Can I mount it outdoors?
No ingress rating is published and it operates from –10 to +50 °C, so plan on indoor or fully sheltered mounting.
