Back in 2018, Heartland Boy had previously written an article on how to maximise the cashback on the UOB One Credit Card. And that was before the crazy period of double-dipping with the GrabPay wallet- a strategy touted endlessly on forums. When top-ups made to the Grab wallet was eventually nerfed, it made some cardholders gave up on the card. However, Heartland Boy thinks that the UOB One Card still holds plenty of promise, with additional cashback awarded to Grab transactions (exclude mobile wallet top up) and SP bills. Here is Heartland Boy’s review on how to get additional cashback with UOB One Card, to be read in conjunction with his previous article to realize the full potential of this credit card.
