Contactless communication interface systems and methods
Embodiments discussed herein refer to systems, methods, and circuits for managing and establishing contactless communications lanes between two contactlessly coupled systems. A contactless communication lane can be formed for each coupled pair of contactless communication units existing in the two systems. A contactless communications interface can enable software-defined connectivity that manages use of the contactless communication data lanes to enable data communications according to a selected one of a plurality of communications interfaces. The contactless communications interface may serve as a protocol translator and virtualization layer for enabling higher level software such as an operating system of a first system to communicate with a second system without requiring interface protocol specific hardware and software. This advantageously simplifies hardware and software components needed to simultaneously service a multitude of interface protocols.
