For BKK Bank you can request a 1 year statement from the mobile app and print it off, as i recently had to do at map Ta Put as there were months in my bank book with no entries, this was the first time they have asked me for it. I have now set up a 1 monthly schedule in the BKK bank app to transfer 100 baht each month to my retirement account so each month has an entry in the passbook.
