Zusammenfassung:A system (15) of an antenna (27) connected to a controller circuit (17) that communicates information with a device host (16) of the system (15) over a contact host interface (18, 22.1, 22.2) to transmit and receive information over a contactless interface (28) of the antenna (27), which the controller circuit (17) comprises a controller processor (24) and a hardware I/O controller (30), which are connected to a front-end module (26) of the controller circuit (17) to transmit/receive processed information to/from the antenna (27) and , which controller processor (24) is powered in a first mode of the controller circuit (17) to process the information and which hardware I/O controller (30) processes the information in a second mode of the controller circuit (17), when the power of the controller processor (24) is low or down.
