Samsung introduced Samsung Wallet in February this year, an app that was available through Samsung Apps on the Galaxy S3, S4, Note and Note II but is now downloadable from the Google Play Store. The app is free as always, but seems to be limited to U.S. customers at the moment, and also doesn't support any more devices than it did before.
Samsung Wallet is basically a digital wallet that lets you store coupons, tickets, gift cards, and more, with the ability to sync all content between all your Samsung devices. You can discover grocery coupons, get time and location-based reminders for tickets, etc., though unlike Google Wallet, there's no NFC or payment system integration yet.
