Read QR Code

QR reading is unavailable. Two things to install:

1. pip install pyzbar
2. The ZBar shared library: install instructions (Windows DLLs ship with pyzbar; brew install zbar on macOS; apt install libzbar0 on Linux)

Then restart the server.

Best results on: sharp, well-lit images of QR codes that fill at least a quarter of the frame. Blurry, tilted, or partially obscured QRs may not decode. Multiple QRs in one image are all decoded.
