Pretty much only savings accounts available; some with fixed time options to get better interest.
Also Thailand imposes a 15% tax on interest earned.

agreed the IDP is nothing more then a translation document not sanctioned by any government entity.
However at least one car rental agency on Samui required it to rent a vehicle in advance online.

Krungsri will NOT do it on a tourist visa alone. Your father will need at a minimum the O or O-A visa, a Thai address with TM30 and then whatever else each individual branch asks for.
