does spending by supplementary card holder count towards rebates?
does the main card holder need to meet the minimum amt every month, if there's spending by supplementary card holder?
Supplementary card spendings counts towards your spendings.
But this is UOB ONE, this card needs discipline. Better spend from yourself than to allow other to help you, since you don't get to enjoy the rebates from overspending (i.e keep closely to the 300/800/1500sgd monthly).
