I was wondering if anyone knows of a QR code scanner module to use in anvil. I checked out anvil extras and fuond alot of neat things, but no scanner. If anyone has any information on this that would be great.
Very basic app that uses the FileLoader component to upload an image to the server.
The server code then reads the codes in the image using pyzbar and returns a list of the decoded data from each code.
It does work with multiple qr codes in the same image but could do with some tweaking on the image before reading it to reduce errors in reading.

Here’s one that the community made.
I seen this it takes the qrcode that is uploaded. I’m looking capture the qrcode with a camera. Either the computer camera or phone camera.

Here’s the example app, which embeds the example you just linked to:

And here’s how I did it:
1. Import the Vega embedding libraries …
