Unreadable barcodes

Hi everyone,

This question follows a discussion with CommCare’s developers :

One on our applications is making heavy use of barcodes / qrcodes. Some external
factors can make reading barcodes harder than it should :

  • light (indoor / outdoor, day / night)
  • barcode itself (is it damaged ?)
  • handset camera (cheap devices with bad camera can fail to read barcodes easily)

I was thinking about an User Interface tweak to fix this issue, but there are very
good reasons why such a solution would be a bad idea.

For your projects, do you sometime have issues reading barcodes ? If so, how do you
react ? What if a barcode or the lighting conditions are so bad that you just cannot
read the code ?

Many thanks,
