Instarem Amaze is a prepaid card that allows you to make overseas payments without foreign exchange (FX) fees. It also offers its own rewards programme called InstaPoints, which can be redeemed for cashback or travel.
The Citi Rewards Card is a cashback card that earns 4 miles per dollar (4 mpd) on the first S$1,000 per statement month spent on offline retail shopping and online transactions excluding travel.
When you link the Citi Rewards Card to your Amaze card, all transactions made with the Amaze card will be converted into online transactions, so you can earn the full 4 mpd on all your spending, even on offline transactions.
