patent by the inventors Kargl, Walter (Graz, AT); Ehrlich, Edmund (Grambach, AT), filed on March 4, 2011, was published online on December 31, 2013. The patent's assignee for patent number 8616456 is Infineon Technologies AG (Neubiberg, DE). News editors obtained the following quote from the background information supplied by the inventors: "RFID (radio frequency identification) communication systems are used in many fields, for example security applications, access controls, payment systems, tagging and tracking items, etc. In this case, passive RFID transponders are integrated into chip cards or tags, for example, and are read or written to with the aid of an RFID reader. In this case, the RFID reader uses inductive coupling to provide the energy needed by the passive RFID transponder to process and transmit data."
