At this time, the service is limited to Japan, but the fine print suggests that a global rollout may be in the works for the near future. “iTunes Pass is not available in Brazil, China and Turkey,” the fine print reads.

Apple first introduced Passbook in iOS 6 as a centralized app which stores boarding passes, tickets, gift cards, coupons and membership cards.  Since its inception, companies such as Starbucks Corp. (NASDAQ:SBUX) and United Continental Holdings Inc. (NYSE:UAL) have used the app for their respective Starbucks Card and United Airlines boarding passes.

Prior to the introduction of iTunes Pass, Apple iTunes users could only add balances to their account through a credit card, physically purchased iTunes Card or iTunes gift code.

While this service may be of limited use in credit card centric countries, iTunes Pass may prove to be an essential service in countries that still predominately conduct purchases in cash, such as Japan.
