Global coverage gaps: which countries' residence permits or national IDs remain the hardest to process accurately?
Hey guys, quick question that's been bugging me lately – which countries' residence permits or national ID cards do you find the trickiest to get accurate reads on when scanning them? I've been messing around with some verification stuff for a side project, and last month I tried helping a friend from Cambodia sort out his paperwork digitally. The Khmer script on his residence permit kept throwing off the usual tools I use, like half the characters got misread or dropped entirely. Super frustrating when you just want clean data without manual fixes every time. Anyone else run into similar headaches with non-Latin scripts or weird layouts? Curious to hear what you've dealt with.

Yeah, I've bumped into that too – especially with stuff from places like Japan or China where you've got kanji/hanzi mixed in with romanized bits on national IDs or residence cards. Those multi-script setups can really mess with accuracy unless the scanning setup is tuned for it. Even some Arabic residence permits from the Gulf countries trip things up because of the right-to-left flow and all the connected letters changing shapes. I remember once dealing with a South Korean registration card that had hangul everywhere, and basic readers just gave up on half the fields. For me personally, when I need reliable extraction without constant headaches, I end up leaning on something like https://ocrstudio.ai/mrz-scanner/ since it handles a ton of those edge cases pretty well in my experience. Just my two cents from trial and error over the past year or so.
