ITunes Gift card instead of Credit Card?

I found some things that i have been wanting on the iTunes store but i do not have a credit card registered with my account. If i were to buy an iTunes gift card, would that work in lieu of the credit card requirement?
Also, the apps that i want to get are for the iPhone. Would buying an app with the gift card affect the plan with the phone in any way?

Yes. Gift cards can be used just fine. No it wouldn't. Has nothing to do with that.

  • How to use my iTunes gift card without having to verify my billing information? I just got the iPhone 5. Prior to this, I had the iPhone 4 and I accessed my iTunes account from that. Then I started using my iTunes account from my dad's computer. Out of the blue, it started telling me that I couldn't even download a free app without verifying my billing information. I tried doing this, but the security code on my dad's card wouldn't work. Shouldn't I be able to use my gift card without having to verify my billing information?
