It appears that Apple Pay may launch in Switzerland just as Apple is kicking off WWDC 2016. A new report from Swiss finance news site Finews.ch indicates that the payment system could arrive as soon as Monday, June 13. They may have at least one major Swiss bank lined up for the launch.
From Finenews.ch (translated from German, via 9to5Mac):
Financial partner of Apple Pay in Switzerland is apparently Ticino Cornèr Bank, which already cooperates well outside the industry with Swatch in Fintech sector.
Apple Pay has been on a bit of a streak this year, arriving in countries like China and Singapore, while receiving expanded support from Canada, Australia, and the U.S. The system is also expected to launch in Spain and Hong Kong at some point this year.
