If was me, I'd a bit concerned. Not (just) about the 2000฿ fine, but about someone massive gathering main private data - not only full passport data with scans, but full house registration data with scans too. Identity theft is a thing, sadly...
Yes, I can screenshot that, but I was thinking it couldn't be so clumsy... TiT
I mean, I could code a button to print a decent PDF from those data in a couple of hours... it's beyond my understanding why the f they didn't it. But again, TiT
Some provinces require re-register if you travel to even other provinces, others only require it if traveling abroad, and others don't require at all if you're returning to the previous registered place.
if you just stay as a tourist for short term it's not a problem. But for everything that needs a visit to immigration it's required: 90 days report, extending your visa, buying a re-entry, getting a residence certificate...
maybe because it's restricted to Thailand and you have your Google Play account configured in other country - it's the same with the DLT app, or the LineMan apps, by example.
