Do I need to provide proof of funds, onward flight, and accommodation when entering Thailand on a visa exempt stamp at the Kanchanaburi border?

I ask because IF you're entering thailand from burma (as in not just bouncing out of thailand and back in) you COULD be asked for proof of funds, onward travel, hotel booking

BUT

If all you're doing is border-bouncing <- stamping out of thailand, stamping in&out burma and right back into thailand you will NOT be asked for any of that at that crossing point.

So you are IN burma now and intending to enter thailand at the Phu Nam Ron border in kanchanaburi?

OR are you in thailand now and just going to border-bounce there to get a 30 day visa exempt entry?
