I only use True money for 7-11 😂😂😂 also difficult for Thai people to use. For Mrt I bought Rabbit card and top up money. Soon they gonna release new card for Mrt name “Mangmoom EMV” but I prefer Rabbit card because can pay for some food court and have many collections 😍
I recommend you to apply True money to pay 7-11 and some restaurants ,it’s very convenient. And you also can use your Visa card to pay. Some shop in shopping centers don’t accept cash anymore. And for online shopping better if use Cash on Delivery.
In the future if it’s easier to apply bank account I recommend TTB bank it’s very useful and only pay for debit card 350thb/year.
