Can I use my bank to buy apps?

My iphone is iPhone 5. I do not have a credit card and my dad isn't willing to give it to me. I do have a bank account which is posb and I live in singapore. I can't buy the gift cards here which freaking sucks like hell. Help? Can I use my bank info to buy apps instead of using credit card?

Added (1). Like I said, I don't have any cards like bank card because my parents says its more secure to withdraw at the bank then at the ATM machine cos people may easily steal your bank card. Uh… Well.

Do you have a bank card?

You can't just type in your bank information, you'll need a card. And you should have a bank/debit card, since you have a bank account.

No they only accept the cards or a credit card the may accept Paypal i don't know
