Provided in a reception device () for receiving a transmission signal (US) in which, adhering to a communications protocol, reception data (ED) can be transmitted to the reception device () from a transmission device () are reception means () for receiving the transmission signal (US), and evaluation means () for evaluating the received transmission signal (US) and for emitting a bit sequence (BFT) received in the transmission signal (US), which bit sequence (BFT) may contain bits of reception data (ED) transmitted from the transmission device () but also bits (SB) occasioned by an interference to the transmission signal (US), and checking means () for checking whether the received bit sequence (BFT) infringes a rule of the communications protocol, wherein the reception device () is designed to continue with the reception of the transmission signal (US) and the checking of the received bit sequence (BFT) following the occurrence of an infringement of the communications protocol.

Transmission error resistant reader station

A data carrier ( ) for the transfer of communication data (KD , KD ) via at least two interface means ( ), having first interface means ( ) for receiving a first communication signal (KS ), and having second interface means ( ) for receiving a second communication signal (KS ), and having processing means ( ) to which a first clock signal (TS ) derived from the first communication signal (KS ) or a second clock signal (TS ) derived from the second communication signal (KS ) can be applied for the processing of the transferred communication data (KD , KD ), and having reset means ( ) for resetting the processing by the processing means ( ), now includes a first frequency sensor ( ) which is adapted to supply first frequency reset information (RI ) to the reset means ( ) when a first clock frequency of the first clock signal (TS ) or the frequency (FKS ) of the first communication signal (KS ) lies below a first lower frequency threshold (FU ), and includes a second frequency sensor ( ) which is adapted to supply second frequency reset information (RI ) to the reset means ( ) when a second clock frequency of the second clock signal (TS ) or the frequency (FKS ) of the second communication signal (KS ) lies below a second lower frequency threshold (FU ), the reset means ( ) being adapted to reset the processing by the processing means ( ) when the first clock signal (TS ) is applied to the processing means ( ) and the first frequency reset information (RI ) is received or when the second clock signal (TS ) is applied to the processing means ( ) and the second frequency reset information (RI ) is received.

Frequency sensor for each interface of a data carrier

A data carrier ( ) includes a chip ( ) having a supply voltage circuit point ( ), from which a supply voltage (V) can be taken, and having at least one supply voltage output ( ) for supplying a supply voltage (V , V ), and having potential control means ( ) to which a control signal (S) can be applied and with the aid of which the supply voltage output ( ) can be set to different potential values in accordance with the control signal (S), and also includes at least one component ( ) which is spatially separated from the chip ( ), which component ( ) has a supply voltage input ( ) is connected to the supply voltage output ( ) of the chip ( ) via a connection lead ( ).
