The technology used to process documents with your phone camera is particularly sensitive to lighting.
We’ve found that positioning your ID in bright light and making sure there’s no reflective glare on the document (passports in particular can be rather shiny!) is the best way to get a good result.
Another alternative is to use a full UK driving licence if you have one. We’ve found that the contrast on these means that the details are easier for your camera to pick up, even in poorer light.
If you’ve tried all of the above and you’re still struggling, just get in touch and we’ll see how we can help.
