Samsung Wallet is available for the Samsung Galaxy S4, Samsung Galaxy S III, Samsung GALAXY Note, Samsung GALAXY Note II, Samsung Galaxy Note 10.1, and the Samsung Galaxy S II HD LTE. The app is available in Korea from Samsung's own app market.
Google Now has similar capabilities and can display boarding passes and Fandango movie tickets. But not all Android devices in Korea have been updated to Android 4.1.2 which is necessary to receive Google Now, and this has left a crack open for Samsung Wallet.
