Cads: it's not too late to give a virtual Valentine's Day gift. Starbuck's app stays live until Thursday. It's part of the Starbucks Cup Magic App program developed last year for the holidays to allow its customers to share augmented reality experiences. The short-term program has Valentine’s Day-themed coffee cups with red hearts. Consumers can download an app and send Valentine’s Day greetings through augmented reality technology that interacts with the cups. Users tap the “Send a Virtual Valentine” button to send the message. Recipients can scan a limited-edition Valentine’s Day Starbucks cup that reveals the sender’s message of love. The app can be interacted with in a number of ways like blowing into the phone to create a pinwheel of hearts or tapping the screen to scatter hearts in the air.
