@sumitsum is it an option to use a service to generate QR codes and display them as an image in the image widget?
What would they want to generate QR codes for? Could you find a few more details?

[sumitsum]

Hi @areyabhishek, user wants to generate the QR code and display it in the image widget:
I want to be able to convert the address-string (e.g. "d49931814e6bfbb8e221f1b2936e206e5a6b6abeb9c070f8603814c525c9abe3") into a qr-code and display it in a img-widget like @Abhishek Nayak suggested on the github-issue.

@sumitsum I believe abhishek is suggesting that you can ask the user to call an API like this
https://www.qr-code-generator.com/qr-code-api/
which will return a URL and then the user can bind that to the Image widget

[sumitsum]

@Nikhil-Nandagopal Sorry, I misunderstood. Got it now. I will respond to the user with this suggestion.

@Nikhil-Nandagopal @areyabhishek Should this instead be the ability to scan a QR code and connect to an API for fetching some record from the DB/Datasource?

[Nikhil-Nandagopal]

@somangshu this particular case is about a special image widget that takes in a text and displays a QR code. It's an encoding solution.
The case you are talking about is also valid but can be an action which triggers a camera and decodes the QR image back to text. i.e a decoding solution

[somangshu]

@Nikhil-Nandagopal Yes, There was a user who wants to build a QC app for their logistics chain and wanted such an option to quickly access the SKU which needs to be QC'ed. Should this be raised as a separate issue?

[Nikhil-Nandagopal]

@somangshu yeah separate issue please

Hi! My use case is the following.
A first user shows a QR that represents certain article which is an entry in a table so a second user with a different role can scan that qr and validate that article and perform actions in their end.

[Nikhil-Nandagopal]

@st-trade you can generate a QR code using the API below and display it in an image widget
https://goqr.me/api/doc/create-qr-code/

You can then use the camera widget to capture the QR code, upload that to S3 and use this API to decode it
