Data storage and communication system

摘要

A portable data storage and communication system includes a disk-shaped device having at least one universal contact symmetrically arranged about a center of the disk-shaped device. The disk-shaped device has at least one electrical component arranged therein which is coupled with the universal contact. An interface device receives the disk-shaped device and has at least one defined interface contact. The interface contact operatively couples with the universal contact regardless of the orientation of the disk-shaped device in the interface device.
