Blur a QR code in a photo

The barcode on a boarding pass holds your name and booking reference, which is often enough to open the booking, change seats or cancel the flight. Event ticket codes can be copied and used before you arrive. Parcel labels carry your name and address, and the tracking code.

Blurring the printed name is not enough when the code next to it says the same thing. Anyone can scan a code from a photo on their screen.

Every QR code and barcode the reader can find is boxed and covered with a margin. You can drag to cover anything else (a name, a booking number) and tap a box to remove it. Pixelate turns the area into about ten big blocks, Blur softens it heavily, Black box hides it completely.

Before saving, the finished photo is scanned again. If any code can still be read, it tells you instead of saving. The saved photo is redrawn, so it also leaves out the photo's location and camera details.
