Abstract
An RFID communication system comprises an NFC device () and a smart card () with contactless card functionality, wherein the NFC device () and the smart card () are couplable to each other via a protocol converter (), wherein the NFC device () is coupled to an antenna () to receive electromagnetic signals (ES) from an RFID reader/writer and to transmit response signals (RS) to the RFID reader/writer by modulating received electromagnetic signals (ES). The electromagnetic signals (ES) contain first and second characteristic components (FE, RE) which define the begin and the end of a predefined signal pattern (PA), wherein the second characteristic component triggers a predefined response delay time (FDT) at the expiration of which the RFID communication system has to respond to the RFID reader/writer. A device () for compensating signal delays is provided that comprises signal pattern shortening means ().
