In a French train I tried to scan this QR code:
I could not scan it, neither with the Camera app, nor with CodeReader. In the Telegram group someone suggested to change the colours (darker, higher contrast) of the photo. CodeReader still could not read it.
Try to scan a green barcode. Others have tried to scan the same image without result.
A scanned barcode
An Android app “QR Scanner”, installed through F-Droid, could actually scan the barcode. Android phones and iPhones as well.
