Google's Android Pay has formally entered Hong Kong and will be available in many local banks and retail stores catering to the nearly eight million residents living in the Chinese Special Administrative Region.

Android Pay is a "one-click payment" service launched by Google. It features NFC communications technology and can be used on devices starting with the KitKat 4.4 Android system.

Android Pay is similar with Apple Pay, which supports rapid and convenient payment functions via smartphones. Apple Pay launched in Hong Kong and mainland China earlier this year.

Android Pay has established partnerships with the Bank of East Asia, DBS, Dah Sing Bank, Hang Seng Bank, HSBC, and Standard Chartered Bank in Hong Kong. At the same time, Android Pay gained support of over 5,000 retailers, including 7-11, Circle K, Fortress, Mannings, Maxims Cakes, MX, and McDonald's.
