If you make regular purchases of apps, games or other content through your Apple ID, you will know the process. But did you know that you can add money directly to an Apple ID, ready to be used? How to use.
Making purchases with your Apple ID is super easy, but there may be times when you want assets available ahead of time. You may want to set yourself, or someone else, a replacement for apps or games, for example. Adding money to an Apple ID is a great way to do that, rather than making ad hoc purchases and possibly losing track of how much you spend.
Adding money to an Apple ID is super easy and all you need to get started is to have a payment method on file. Doing this is the steps you can take to add any amount to your Apple ID.
Adding Credit to an Apple ID
To get started, open the App Store on your iPhone or iPad, and then tap on your avatar at the top of the screen.
Next, at the bottom of the screen, tap "Add Funds to Apple ID". 
You now see a series of preset amounts, including $ 10, $ 25, $ 50 or $ 100, but you can press "Other" to enter a customized quantity if you wish. Make your choice and press "Next".
At this time, you will be prompted to authorize the transaction via either Facial ID or Touch ID, depending on which device you are using. If it's not available – if you're using an older iPad, you'll need your Apple ID password.
Once you have authenticated, the Funds are added to your Apple ID, ready to be used the next time you make a purchase. Any additional amounts will mainly be treated as a gift card.
