It’ll only be a matter of time before iPhone owners in China can start using Apple Pay. Corroborating a lingering rumor by 9to5Mac, the latest iOS 8.3 beta shows references (via Twitter user Khaos Tian) to China’s Union Pay.

Since launching in October, Apple’s digital wallet service has only been available to those in the U.S., but it looks like Apple is ready to take on the biggest market of them all.

China was a big part of the iPhone’s tremendous growth this past quarter, so it’s no surprise to see Apple making that market a priority for its Apple Pay service. If an agreement with UnionPay is made, it’ll give consumers one more reason to opt for Apple’s newest iPhone 6 and iPhone 6 Plus.

The code clearly shows China UnionPay as a supported bank card organization; Union Pay is the only domestic organization in the People’s Republic of China.

Although support for the bank card looks imminent, it doesn’t mean Apple will make any major announcements anytime soon. We’ll definitely keep our eye on this one as more evidence is found. For now, it sure looks like China is the next big market for Apple Pay.
