Samsung Pay version 2.3 adds support for some more gift and membership cards to make the service more useful. Card Restore is a new feature in this version which enables users to restore all of their membership, gift and Samsung Rewards cards when they sign back into Samsung Pay. As previously mentioned, the iris authentication feature is limited to the Galaxy Note 7 only as it's the first Samsung smartphone to feature an iris scanner. The updated app is now being rolled out to users in all supported markets.
