Hi there! Good that at your age as a nsf you love to save, invest and learn ways to save and also bloom your money. During my time in ns, I opened up a POSB saye account and it really helps to discipline your saving skills or method as it auto deduct your amount you wish to save. This account I must say is a must to open!! Safra debit card would be good because the ammenities at safra for example if you life to swim is free! It’s just the few months they will deduct a portion of your pay up to $90 monthly but only for like a few months from what I recall. As I just ord this year July:) Currently, I have 3 accounts with DBS. It’s good for savings, expenses and an account to keep for your let say holiday or future planning in let say 2-4 years. You can do it!
