Was in BKK bank today getting a new passbook. I mentioned that the Union Pay was useless outside Thailand.
They informed me they will be switching to a MasterCard based card. But could not provide a date when the transition will occur.
Bangkok Bank switching from Union Pay to Mastercard
Re: Bangkok Bank switching from Union Pay to Mastercard
Yay! I see the Union Pay announcement every time I use an ATM and was dreading the date when my Visa-branded card expires.
