This sounds like a really neat feature. I am very near-sighted and wear glasses all the time, but even still, it's hard for me to see all the tiny numbers on gift cards, credit cards, etc. I wonder if this works with all webcams or only with certain ones...
Redeem iTunes Gift Cards via Camera in iTunes 11
In Apple’s just-released iTunes 11, users visiting the iTunes Store to redeem gift cards have a new option allowing them to simply take a photo of the code on the back of the card with their computer’s camera in order to redeem their cards.
The option, which requires a card containing a box around the code to assist with recognition, allows users to quickly and easily redeem gift cards without having to worry about accurately typing in the unique 16-character code. Users are also still allowed to enter their codes manually for redemption.
