Data exchange method using data recording carriers involves transferring reception data and operational energy for electronic circuit chip in form of carrier-frequency electromagnetic wave

摘要

The method involves transferring the reception data and operational energy for an electronic circuit chip (2) in the form of carrier-frequency electromagnetic wave so that a light sensitive device (3) generates and transmits electric signal to the circuit chip corresponding to the reception data through a light beam. An Independent claim is also included for flat data recording carriers.
