iTunes 11 has a really neat new feature that lets users redeem a giftcard without typing in a single character. Users can simply hold their giftcard up to the FaceTime camera on their Mac and iTunes will read the code and redeem the value for it.
This is the greatest feature Apple has ever invented. No longer shall consumers be subjected to really long funky alpha-numerical gift codes as we hunt-and-peck our way through entering the code into our computer in exchange for some free iTunes bucks.
