Previously, Apple users were only able to pay for transactions using a registered bank card or gift card. The new option means it's now possible to make purchases across iPhone, iPad, and iPad touch and Mac using a PayPal account. To select PayPal in the payment method options on iOS, go to Settings -> iTunes & App Stores and tap on your Apple ID, then select payment information. The same options can be found in iTunes on Mac or PC via the Account Quick Link.
Once users have updated their account settings for the above services, all future purchases made with the customer's Apple ID will be automatically charged to their PayPal account. This includes purchases of apps, music, movies, TV shows, and books, as well as Apple Music subscriptions and iCloud storage.
The new payment option brings PayPal's One Touch service to Apple accounts for the first time, meaning users can purchase from all Apple devices including Apple TV and Apple Watch, since they don't have to sign in every time they want to make a transaction. PayPal said the system provides a "secure and versatile payment method to meet the growing demand for digital entertainment."
