PORTABLE ELECTRONIC DEVICE, EXTERNAL BASIC DEVICE, METHOD FOR COUPLING THE PORTABLE ELECTRONIC DEVICE TO AN EXTERNAL BASIC DEVICE AND USING THE EXTERNAL BASIC DEVICE FOR COUPLING THE PORTABLE ELECTRONIC DEVICE

摘要

A portable electronic device includes a functional processor for providing an electronic functionality, an optical data transmitter for conductor-less, optical data communication with an external basic device and an energy supplier for an energy absorption by means of an inductive coupling from a magnetic field emitted by the external basic device and for supplying the functional processor and the data transmitter with energy based on the energy absorbed from the external magnetic field.
