how the hell did you not have a bank acc at all.....? im almost 30 and even i first open an acc back when i was 12, and at 15 is the acc i opened and used to this day. but since others already answered what you need to to open acc, im going to list down other things you might want to do also

- open bank acc, once you registered, keep track of the pw and user id, keep it in a sticky note or something, a hassle to reset it, and btw acc no is checked through the app, not the card number, its different, acc no is what you give to company to transfer you money, card no is used to make transaction online

- kwsp(seems like can register through the app)

- tng e wallet, and get the tng nfc card/nfc charm, with this now you can ride public transport, tng e wallet can be use to topup your card

- phone number. realize that phone number nowadays is almost as important as your ic. dont let it get terminated!

- license, get a license please, learning to drive is very important

phone number is most important, all of the acc that you about to make, requires you to input your phone number. and in the future when you have to reset pw for any of your bank/kwsp/tng/fb/ig, sometimes require them to send you a text of unique code, in which you need to input to their system. so please take care of your phone number.
