You can use Kinect to redeem a printed Xbox One gift card, giveaway or any other QR code accompanying a promotion. You can still type in the code manually if you wish.

Call out to the Xbox Kinect using the voice command, "Xbox, Use a Code." This will activate the Kinect to view the room you are in. Hold up the retail code that you purchased at a retail store, such as Target or GameStop, which will be in the form of a QR code. By holding the QR code close enough to the Kinect camera, the Kinect will automatically read and redeem the code for the software you have purchased within seconds. The download will start thereafter.

Note: The Kinect is able to read QR codes out as far as 6 feet.

A Vine exists of Major Nelson redeeming a QR code via the Xbox voice command, as well.[1]

QR CODE GENERATOR

Various websites/apps out there will allow you to turn your 25-character codes into QR codes for easy Kinect redeeming. You can then print them out or display them from your smartphone.

Manual Entering

You can also use the old fashioned way of entering an Xbox One code. Go into the Xbox apps to find the "Use a Code" portion of the menu system. You may have to thumb through it to the right a little bit. Once there, select to enter the 25-digit code manually. Scratch off the numbers on the back of the card that you purchased and type them in individually. Your content will unlock thereafter.

Smart Glass

In addition to Kinect or Manual entering, the Smart Glass app can be used as a remote keyboard for entering codes. This is probably easier than typing from the controller.
