Thegreeting cardsthat play thesongsthey love. Celebrate the special moments with the songs that say it all. Bring back the memories, Let the lyrics do the talking. On the front of each card is a key song lyric. On the reverse there is a scannable code that is activated with a smartphone that links through to the chosen song. The song is activated to play by opening a smartphone camera and pointing it at the code.If you have an android phone, you may need to download a QR code reader. When you point the phone camera at the code you will be taken to a holding page that enables you to pick your streaming provider to listen instantly to the song. If you dont have a premium account through Spotify or Amazon Prime, select YouTube for instant streaming. Song:Signed, Sealed, Delivered (I\'m Yours)Artist:Stevie Wonder
