System for the contactless exchange of data, and responder for use in such a system.

摘要

Disclosed is a system for the contactless exchange of data between one or more transmitter/receiver devices and a plurality of responders. According to the invention, at least one of the responders is designed to exchange data via a microwave connection with a transmitter/receiver device operating in the microwave range, and to exchange data via an inductive coupling with an inductively operating transmitter/receiver device. <IMAGE>
