Found out about this recently. A good card if you want miles! Gives 4 miles per dollar spent if you use paywave (but only if you spend a minimum of $5)! Also gives 4 miles per dollar spent on popular sites such as fave and qoo10!
Downside is, it took me 5 weeks to get the card. I applied for it, called them 2 weeks later when I didn't receive the card, and they said the card was likely lost in mail. They sent me another, and the same thing happened. Called them again, and this time I received it one week later. Took a total of 5 weeks to receive. Not sure if UOB or SingPost is at fault.
