BARCELONA — During its Developer Day at the Mobile World Congress, Samsung has unveiled its Wallet app for Android.

Similar to Apple's Passbook, Samsung's Wallet will let users keep all their coupons, various tickets and membership cards in one place.

A service such as this one is only as good as its partners, and Samsung has announced a decent roster, including Hotels.com, Lufthansa, Expedia, Walgreens, Belly, Major League Baseball Advanced Media and Booking.com.

Partners will be able to use the Samsung Wallet API to provide time real-time updates on membership card points and changes to boarding passes as well as location-based push notifications.

The API is currently in beta and available to selected partners, but it will open to the public in May 2013, Samsung says.
