Paying with Google Wallet/Apple Pay/ Samsung Pay is available more than people think. It is just a RFID payment the same as actually using a card. You can use it anywhere they have a machine for touch card payments (Usually called contactless payment). 711, Big C, Lotus's, Fuel Stations, Starbucks, Tops etc. The only problem is the staff invariably do not know how to do it. So what I do is wave my BB debit card but don't let them take it and as I go to touch the machine with the card I use my phone instead. They often say I haven't paid yet but when they look at the till the transaction has gone through. Transactions over 1500 baht require your PIN. One place did ask me to put my card in before it would let me enter the PIN - I can't remember where now. It didn't matter to me as I had a physical Wise card but that could be awkward with a virtual card. There has been a guy on this forum who claims he got his Wise card sent to his Thai address. It could be something to do with where you declared being tax resident to Wise. My account is based at my UK address and I obtained the card when I was in the UK. It only allows 2 free ATM withdrawals a month so being able to load the card and make payments could become invaluable.
I can set up Google Wallet on my Samsung Galaxy Watch, so I will do that next and upset the girl at Starbucks 🤣
