This document discusses Linccer, a platform that allows for intuitive information transfer between nearby devices without requiring user accounts or pre-shared identifiers. Linccer uses environmental grouping and low latency transfer to connect devices and provide spontaneous sharing of data through gestures like dragging content between screens or throwing and catching digital items. The Linccer API is designed to be flexible, platform independent, and easy to use to develop various location-based applications beyond just Hoccer's example use cases.
