What is a good Debit Card that a 16 Year Old student can apply for?

DBS Debit Card for sure. Gives you 3% cashback for min spending of $400 per month. However, do read their terms and conditions on the eligible spendings

Hi Ansel,

I would say probably the DBS Visa Debit. There is a 3% cash which does require you to spend a minimum of S$400 on Visa and keep your cash withdrawals to S$400 and below in the same month. If you don't spend that much then get the OCBC FRANK debit, or the UOB direct Visa debit, depending on your bank account that you have.

IMO, the real hacks come when you have access to miles cards, and that's when you turn 21. You'll have a life time to maximize your credit cards at that point. Just 5 more years to go.
