I'm strongly considering moving to the Hua Hin area later this year as a newly-retired, first-time visitor to the kingdom. What am I required to carry with me during those mostly sweat-drenched and sometimes rained-upon rides as far as passport ID is concerned? Do farangs carry a paper copy of their passport or even the actual passport in some sort of case, or is their some credit card sized ID format that suffices as legal ID? Am I misjudging the importance of carrying such identification in the first place?
