In addition to paying at 7-Eleven and taking care of utility bills, it also offers a virtual Prepaid Mastercard that can be added to Google Wallet. I find this convenient as it enables me to pay with my watch.
No. What you will get is a multi-entry visa with a validity of 5 years giving 180 days permission to stay each time you enter the country, with the option, once per entry, to apply for an extension of the permission to stay with a further 180 days.
I originally set up my account while living in Denmark. When I moved to Thailand I changed the address to my Thai address. I don't recall having any issues doing that.
Yes, that makes sense.
(I'm sorry that I phrased my reply like that. I misinterpreted your statement about not knowing to be a question. I apologise for putting words in your mouth.)
Perhaps your own quote answers your question: I.e., the amount of THB needs to be already in Thailand to cover your transfer and, if not, they will have to delay until they have enough THB locally to put into your account.
Could be that it just means removal of something like the requirement for police record and doctor's certificate currently needed when applying for an O-A.
Yes, they do indeed. And the best thing about those (i.e., contactless payment terminals) is that there's even no need for fumbling with a card. I just hold my watch to the terminal and payment is done. I don't think it can be any easier than that.
