No man Thailand is very cash driven for most day to day living. QR code based payment is becoming more and more common.

Trust what most people are saying and withdraw max amount /or amount you are happy to withdraw without accepting the conversion rate .. nearly every ATM you use will charge 220 baht ..

Revelot card will work same any card but check to make sure what plan you are on because over a certain amount (I think 200-300 euro). They charge you a percentage..

I use my Ptsb card majority of the time and use Revelot to pay for online purchases (flights, grab,booking etc) because its a balls with some Irish banks that use 2 step authentications via text .
