Pointcast Mobile Connector is a patented technology that allows contactless communication between mobile devices and interactive displays through high-frequency sound signals. It consists of signal emitters, an encrypted high-frequency signal, and receiver plug-in software. The technology is being used in campaigns by Coca-Cola and Orbis to automatically collect digital stamps on a participant's phone when they are near a checkpoint. Pointcast is partnering with developers to license their signal and SDK to enable contactless features in mobile apps. They have over 100 developer partners and have launched successful campaigns for clients.
