The best

The best QR and barcode scanner I have found so far.
I have tried out a lot of scanners and some do not even seem to scan the simplest codes.
This app is able to scan some very complex QR code.
I use this for scanning QR stickers on our fire extinguishers, which contain our email address and serial number and identification. Makes keeping track of multiple locations a lot easier, and provides for documentation for monthly inspection.
