Tourists and expats required to aways carry photo identification

It's nothing new, it's been the law for decades in Thailand: 

All foreigners must carry an authorized photo identification.

Every so often immigration officials remind us of that requirement.  The latest reminder comes to us courtesy Hua Hin Immigration, as posted on Thai Visa.

Thai Drivers Licence or  your Passport are acceptable forms of identification.

In some instances laminated copies of your passport are acceptable.  The Thai Visa article indicates that "certified" copies of your passport are acceptable in Hua Hin.  

This practice (laminated copies) may not be acceptable nationwide.  I recollect just a few years ago reading of a sweep of nightclubs when copies were not deemed proper identification and fines were issued.
