A reported launch roadmap from MasterCard seems to indicate that Apple Pay will be heading to Japan, Brazil, Hong Kong and Singapore by the end of 2016. The purported roadmap, which was leaked by 9to5Mac, also indicates that Apple Pay may add support for MasterCard in Canada before the end of 2016 as well. Apple Pay in Canada currently only supports American Express cards.
If the launch roadmap is to be believed, 2016 could be a big year for Apple Pay's expansion. The mobile payments platform already made its debut in China earlier in February, and France is also rumored to see a rollout this year.
