Open Source Barcode Scanner

Lets you scan and save, plus create your own QR codes in an instant, even giving them some color if you wish.

This might be useful not only for crypto-related things, but also for invitations, or if you just want to have a reminder you can print out and scan if the surface is not big enough for the message but the QR code.
