EpicMix is an RFID lift ticket system that integrates with an iOS/Android app, website and your social networks to provide the ultimate mountain experience. The RFID chip in each lift ticket tracks you across the entire mountain, and that, combined with the smartphone app and website provides rewards, badges, live friend connectivity and a full rage of stats as you explore the mountain.
