Letting people choose when a photo holds several VCodes
Why the VCode web scanner lists every code in a photo and lets the person pick one, instead of acting on the first it finds.
What I tried
The first version of the web scanner acted on the first code it found in a picture. A page photographed with several VCodes offers several choices.
Why I chose differently
The decoder always found every code in the picture, so the choice belonged to the person.
What I chose
A picture with several codes now lists them and the person picks one. Only the chosen code counts as a scan, so the analytics stay honest.
The principle
Before compensating for a limit, confirm the limit exists.
