QR image read using device camera

I’m considering to collect some simple data with mobile devices. Our colleagues should go around facility, read out some metering devices, and enter this into our web form (dash form). They need to enter readout and serial number of metering device. If I put QR codes on those devices, can our dash web form somehow use phone to activate camera, take photo, and read serial number from QR code?

To my knowledge, there are no current Dash components that can do this. However, if you can figure out how to do it in javascript, you could wrap that logic into a custom Dash component. It might be worth taking a look at the MediaDevices API,

the dcc.Upload might work here

Hi, dnoha, I am also looking for this features. Do you have any updates of reading QR codes via Dash components or workarounds? Any tips will be appreciated.
