Hello. I’m looking for a rewards credit card that can be used to redeem miles (hopefully does not expire) and/or cash rebates. What are your suggestions?

Off hand I can recall, for credit cards that gives you rewards points that you can use to redeem miles and/or other stuff like vouchers, you can choose the following:

1) DBS Altitude Card - points don't expire

2) OCBC Titanium Rewards - 2 years fee waiver

3) Citi Rewards Card

4) AMEX Rewards Card

5) DBS Women Card - Points expire in a year though

There are more but these are the popular ones.

I would suggest the DBS Altitude card! There is no minimum spending to hit, you get free lounge access every year and the miles don't expire!
