Coffee loyalty cards are a popular marketing tool for good reason. Tin Soldier replicated this concept online with the creation of an iOS app for Piazza D'Oro. Consumers simply scan each of their purchases with the app, which accumulates into free coffee rewards over time. The app also includes a geo-location search feature to find the nearest Piazza D'Oro café.
The virtual card is even stored securely on all the user's signed-in devices, so they won't ever miss out on a caffeine reward!
