What does the "O-A" designation mean on a Thai national's entry stamp?

ORIGINAL POSTER

Good afternoon!

Does anyone knows the reason why in the entry stamp, on a Thai national passport holder, is mentioned the letters "O-A"?

As Thai nationals are obviously exempted of Visas to enter in Thailand, why the mention of that type of visa "O-A" as in picture?

SOLVED: O-A mean outgoing automatic door and there's no departure stamp aswell

TLDR : Answer Summary

The mention of "O-A" on the entry stamp for a Thai national was clarified to mean 'outgoing automatic door,' indicating that the individual likely entered through automated gates. Comments also noted that Thai nationals typically don't need a visa for entry and that the stamp could be related to the type of passport used for entry.

already now the meaning. The passport wasn't stamped at departure because effectively it was used an automatic door and this is the code to mention the Outgoing Automatic

A Thai national is only exempt if they enter with a Thai passport. I'd say they entered on some other kind of passport, and therefore they're considered whatever nationality passport they used.

Sounds like a mistake possibly. But I'm only familiar with foreigner passports and stamps, so if there's a Thai reason, I wouldn't know it.
