Congratulations on being born, or working hard, or whatever it was you did to deserve an iTunes gift card, reader! Now's the time to catch up on the first two seasons of Game of Thrones. Before you start typing out the lengthy letters and digits of the redeem code, there's an easier way to transfer the credit to your iTunes account: a quick flash of the gift card to your Mac's on-board camera does the trick.
First step: sign into your iTunes account. From there, click Redeem on the right side of the homepage under Quick Links. On the Redeem Code screen, select Use Camera. Peel or scratch off the code on the back of the gift card, then hold the card up to the camera. The code must be on a newer gift card within a black rectangular outline. Your camera (sorry, PC users, this only works on a Mac computer) will automatically read and process the code, turning the numbers seen on the screen from white to green with the wording "Your Apple ID has been credited with . . . "
There you go! The monetary credit is instantly uploaded to your Apple account, and you can go about your business seeing what treachery House Lannister is up to now.
