Xbox gift card is a prepaid card that can be used to make purchases on the Xbox platform, including the Xbox Store, Windows Store, and Microsoft Store. It allows you to add funds to your Xbox account, which can be used to buy games, downloadable content (DLC), movies, TV shows, apps, and more.
When you redeem an Xbox gift card, the funds are added to your Microsoft account balance. You can then use this balance to make purchases across various Microsoft platforms, including Xbox consoles, Windows PCs, and mobile devices. The gift card amount can be used to buy digital products, such as games and movies, or to pay for Xbox Live Gold subscriptions and Xbox Game Pass subscriptions.
