Smartest A4 Paper

This a prototype for a digital engagement that allowed a piece of plain paper to interact with content on a mobile device. Data was transferred from electronics embedded in the paper to the app via audio encoded message known as Chirps. This was decoded using the Chirp SDK. The circuit was designed to be only 3 mm thick and be embedded in the spine on the edge of the paper. Engineers were engaged and manufactures in China identified.
