86-Box QR Code & NFC Card Reader, Glass Panel, IP54: overview
The QC-190 is an 86-box QR code and NFC card reader with a black glass front and a row of indicator LEDs that brighten in sequence, giving a finished look for lobbies and reception areas. It reads QR codes, 1D barcodes and 13.56 MHz cards and hands the result to your existing controller. The front is rated IP54, which covers dust and splashing water at sheltered entrances.
Its scanning specification matches the embedded QC-180 module: a 72° diagonal field of view, 1/30 s capture, 3–20 cm QR range and tolerance of 360° rotation with ±55° pitch and skew. For cards it follows ISO/IEC 14443A/B at 0–5 cm and handles MIFARE Classic 1K/4K, MIFARE Ultralight, DESFire and CPU cards. It can read encrypted MIFARE Classic sectors and CPU-card content as well as UIDs. iCLASS is listed for card serial number (CSN) reading only; test your own iCLASS credentials before committing.
Integration notes
All versions output Wiegand and USB, with RS485 (QC-190-M-RS), RS232 (QC-190-M-RS232) or TTL UART (QC-190-M-T) as the serial option; output format and accepted card types are configurable in software. Supply 9–24 V DC; current is ≤ 130 mA on standby and ≤ 200 mA while reading. The 86 × 86 × 21.3 mm housing connects through an 11-core lead plus a 1,000 mm USB cable, and a white fill light helps in dim entrances.

QC-190 FAQ
Does the QC-190 read HID iCLASS cards?
iCLASS is supported for card serial number (CSN) reading only; secure iCLASS data is not read. Send us a sample of your credentials and we will confirm the result before you order.
What does sector encryption mean for my project?
Instead of trusting the card UID, the reader authenticates to a MIFARE Classic sector with keys you define, so a card that only copies the UID is rejected. CPU cards can be checked the same way through their stored content.
Can it be used outdoors?
The front is rated IP54, meaning dust-protected and resistant to splashing water. Use it at covered entrances; for exposed lanes, the IP65 QC-180 module is better suited.
Which serial option should I choose?
Pick RS485 (QC-190-M-RS) for controllers on a bus or longer cable runs, RS232 (QC-190-M-RS232) for PC-style serial ports, or TTL UART (QC-190-M-T) for direct microcontroller connection. Wiegand and USB are present on all three.
How far away can a QR code be read?
From 3 to 20 cm. Minimum element size is 10 mil for 2D codes and 5 mil for 1D barcodes.
