A planned expansion of Samsung Pay is the latest in a seemingly endless series of maneuvers made by mobile payment providers throughout 2015.

In an interview with Reuters, Thomas Ko, global co-manager of Samsung Pay, said U.S. consumers will be able to use the mobile wallet solution for online payments in 2016.
