Install QR Code Reader on Raspberry Pi

QR Code Reader

CoBang app - simple lightweight QR code and barcode scanner, uses the webcam.
Not sure if this is compatible with the Raspberry Pi Cameras, but it should work with those if you set one up as a normal video output device.
It also supports importing a picture of a QR code.

To run: Menu -> Graphics -> CoBang
To run in a terminal: flatpak run vn.hoabinh.quan.CoBang

Quick tip: In testing, it seems that the scanned URL is displayed below the bottom edge of the window. It is still there, but you cannot see it. And the scrollbar is one of those auto-hiding ones. To see the URL, you just need to scroll down, or increase the height of the program window.

Fortunately, QR Code Reader is very easy to install on your Raspberry Pi in just two steps.

  1. Install Pi-Apps - the best app installer for Raspberry Pi.
  2. Use Pi-Apps to install QR Code Reader.


For the best chance of this working, we recommend using the latest version of Raspberry Pi OS, which is currently version Bookworm.
Raspberry Pi OS has 32-bit and 64-bit variants, both of which will run on most Raspberry Pi computers, including the Pi 3, Pi 4, and Pi5.
QR Code Reader will only run on PiOS 64-bit. Pi-Apps will not let you install QR Code Reader on PiOS 32-bit.
