发明名称 Device, system and method for compensating signal delays in an RFID communication system
摘要 An RFID communication system comprises an NFC device (11) and a smart card (2) with contactless card functionality, wherein the NFC device (11) and the smart card (2) are couplable to each other via a protocol converter (7), wherein the NFC device (11) is coupled to an antenna (3) 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 (12) for compensating signal delays is provided that comprises signal pattern shortening means (13).
