Hi. I read a lot recommends using the maribank transfer method + maribank cc (for the 1.5% cashback) but there wasn't much discussion or excitement on the DBS Union pay debit card promo which has a 5% cashback and waives 3% if transact RMB200 and more using WeChat pay or alipay. Even if I account for the foreign exchange fees of 3.5%, shouldn't this option be at least on par with the former method? Just wondering. I thought doing away with the need to always be mindful of what payment method to choose is pretty good especially there are 101 things to worry in a holiday trip.
