UOB has decided to reduce the attractiveness of its cards once again.

Do take note of the upcoming changes for payment to educational institutions.
I have extracted the following info from my e-statement:
Wef 1 September 2019, please be informed that:
1) Applicable to all UOB Personal Credit Cards (except UOB Reserve, Visa Infinite Metal, Visa Infinite and Privilege Banking Cards) - payments to educational institutions will be excluded from rewards (base & accelerated UNI$ awarding) and cash rebate (min spend and awarding).
2) SMOOVPAY transactions will be excluded from rewards (accelerated UNI$ awarding) on UOB Preferred Platinum Visa Card.
