1. A device for compensating signal delays in an RFID communication system, the device comprising:

  • an NFC device coupled to an antenna to receive electromagnetic signals from an RFID reader/writer and to transmit response signals to the RFID reader/writer by modulating received electromagnetic signals, wherein the electromagnetic signals contain first and second characteristic components which define the begin and the end of a predefined signal pattern, wherein the second characteristic component triggers a predefined response delay time at the expiration of which the RFID communication system responds to the RFID reader/writer, wherein the device for compensating signal delays includes a signal pattern shortening signal; and

    a smart card with contactless card functionality, wherein the NFC device and the smart card are coupled to each other via a protocol converter.
