Because, we have here something called “Swiss Qr Bill” (standardized e-bill with Qr code) and some shops send you the bill via email. Would be nice, if i could just tap the qr-image and open with app.
“QR & Barcode scanner” is Free an Open Source, and supports what you want (if i understood you correctly) https://github.com/wewewe718/QrAndBarcodeScanner
Looks like it’s not been updated in a while, but it works just fine. Available on F-Droid and on Google Play
URLCheck solves this issue for all links. Just make it your default browser and go from there. Lots of cool settings to mess with inside too including an optional VirusTotal integration!
GrapheneOS’ camera app has a qr code reader baked in
Cognex Barcode Scanner is not open source but it is the best. It’s basically just a demo frontend for a commercial barcode programming library so they are not trying to monetize the app itself. It supports everything! Not just QR code but every kind of barcode. I used to work in logistics and I used it to scan all the different barcodes on shipping labels.
When you scan a barcode you can choose to open, copy, share. Open launches your default web browser. If the barcode isn’t a URL, it all give a search option and you can configure your preferred search engine. It can scan images from your gallery or use your camera. But the important part is it won’t do anything with the scanned data until you tell it to.
