Use the Xbox Live Gift Cards to recharge your credit balance as an Xbox Live member, enabling you to shop the contents offered in the Xbox Live Store. Among other things, you can find Xbox Live Arcade Games, bonus content for Xbox 360 and Xbox One games, Avatar extras or Season Passes there.
You also need a sufficient credit balance to rent or purchase movies in HD or TV series, changing your Xbox Live Gamertag, and more. (Information: Points cards may also still be redeemed. The balance is then credited to the customer in EUR.)

1. Visit https://live.xbox.com/redeemtoken and login to your account.
2. Click the green Redeem button.
3. Enter your 25-digit Xbox gift card code and click Confirm.
