Hi Tod, in a previous post you mentioned this :
When you stamp in to thailand that system matches by, country of origin, DOB, Sex, Age, Surname etc not just a passport number.
They can see your entire entry/exit history going back as far as they want.
How does it work when you have two different passport (bi-national I mean) ? Do they actually can trace all your entries for both passports ? Or the fact they match by country of origin first means they won’t be able to trace the other passport ? Thanks in advance for your insights 😉
TLDR : Answer Summary
The discussion revolves around how Thailand's immigration system manages entry and exit records, particularly for individuals holding dual citizenship and different passports. It highlights that biometric software is used to cross-reference records regardless of the passport scanned upon entry. Users express curiosity about how the system deals with variations in names and records pertaining to multiple passports, with several commenters suggesting that Thailand employs advanced database systems to maintain this information.
