PayPal announced that its payment service is coming to the App Store, Apple Music, iTunes, and iBooks on iOS devices and Macs today, starting in Canada and Mexico with the US and other countries to follow soon. Setting up PayPal works the same as adding a credit card:
Paying with PayPal is simple. Customers with a new or existing Apple ID can select “PayPal” as their payment method from their account settings in the App Store, Apple Music, iTunes [and iBooks] from their iPhone, iPad, iPod touch and Mac, or on iTunes from their PC.
After PayPal is enabled, purchases from the selected Apple ID will be made from the customer’s PayPal account.
Adding PayPal should expand the universe of customers making purchases from Apple’s stores by creating an alternative for people who don’t have or don’t want to use a credit card.
