Apple Pay has officially launched in China, just days after a bank worker accidentally revealed that the service would launch in the country this week.
In a short statement on its developer website, Apple said: “You can now support Apple Pay for your customers in China, providing an easy, secure, and private way for them to pay using their China UnionPay credit and debit cards.”
Users can also pay for goods in stores using their iPhones, coupled with the device’s Touch ID fingerprint security technology.
Apple is being understandably bullish about its prospects, with Apple Pay boss Jennifer Bailey telling Reuters that "China could be our largest Apple Pay market".
However, the company is likely to face stiff competition from Alipay, the mobile payment service from retailer Alibaba, as well as WeChat Payment.
The concern for Apple is that users already have payment solutions available for buying goods online through their smartphones.
Alipay has both iOS and Android apps and 400 million customers across China.
However, Apple says its service will work with 80% of all credit cards in China, after it teamed up with 19 banks and credit card companies.
Apple Pay has been at the centre of the iPhone Error 53 glitch, which saw devices which had had their Touch ID buttons by third parties bricked by an official software update.
