Oh I didn’t know about the cashback part. I have a regular maribank account only. Is thr card a regular credit card or a prepaid debit card like Revolut/Youtrip?
"regular credit card or a prepaid debit card"...depends which one you applied for & whether got a job or not; but it is not a multiple currencies eWallet like YouTrip, Wise or Revolut.
The exchange rates are very close to Google rates ie

, competitive; & no foreign exchange fee.
Trust Card is similar & equally

. Trust as long as got job or monthly CPF Payout can get Credit Card.
