With grab reducing the amount point rewarded for the use of the card will u still use it often or not and why

The card is still useful. Important to take note is some shop offer both paywave(using grab card) and also qr code. It is better to remember to use the pay wave option for more point.

I bought something from Samsung and forget to use the pay wave method and went to scan the QR. Wasted points

I will still use it for non credit card payments (e.g hawker). Just ensure that you topup your GrabPay wallet using cards that can earn you 1.7-1.8% cashback (e.g UOB Absolute Cashback)

Going to stop using grab and try out other payment types.

Still ecent if linked with Shopback
