What is the process of opening a bank account in Thailand with a retirement visa?

I just wanted to share my experience recently opening a new bank account with my retirement visa at SCB in the Isan region.. I am Gen X farang from America, and I already had two Thai bank accounts, one with Bangkok Bank and the other with Kasikorn Bank .. for the Bbank account, I use it only to deal with retirement funds, and it was opened by my visa agent, so I really had nothing to do with it. . For the KBank account, I opened it in the south of Thailand, and it was relatively painless, except that they did require a residence certificate, which entailed a visit to immigration, and then another visit back to the bank branch… For the SCB account opening last week, I showed up with my passport and my one year condo lease , as well as some paperwork about the condo owner, his Thai ID, etc. . Note that I did not bring a TM30.. my purpose of the visit was simply to find out what exactly would be needed to open the new account, to show them what I already have available in terms of documentation, and then I had planned to go back to immigration or to get whatever was needed, before returning to the bank branch next week .. I did not think they would actually open a new bank account for me on the spot .. to my  surprise, they looked at all of my documents, and asked to see one additional form of documentation … so I showed them my newly acquired Thai driver license, Although other forms may be acceptable in lieu of a driver license, I am not sure ..  one of the employees said something about me possibly needing to go to the AIS store to get some documentation about my SIM card, But then another employee seemed to overrule her ..  The only problem was that it took them approximately one hour to scan the chip in my passport; to be honest, I am not sure that I knew passports even contained a chip .. there was a problem with their system, but then they were able to figure it out .. after a total of two hours, I walked out with my new SCB bank account, along with my new ATM debit card and bank book, as well as the mobile banking app that they helped me to download onto my phone .. if not for the passport chip scanning glitch, the entire process would’ve had me in and out of the bank and under one hour….. To say that I was surprised, if not shocked, that I was able to walk out on the same day  after only one visit, with my new bank account would be an understatement .. a very pleasant surprise… also, to be honest, I think it helped that I managed to clean up, put on a nice shirt and appear presentable, ha.. I made sure to go on a random weekday afternoon when I did not think the branch would be as busy as it would be on, say, a Monday morning… and I also made it a point to prepare myself mentally and make sure that I would not get annoyed or frustrated… those things may seem trivial, but in Thailand, I think they actually go a very long way…. Overall, a very pleasant experience… Way to go Thailand, and way to go Siam Commercial Bank . ✌️
