SINGLE COMMUNICATION CHANNEL BETWEEN A CONTACTLESS FRONTEND DEVICE AND A TRANSCEIVER DEVICE

摘要

Method for exchanging data between an NFC device (10) and a transceiver device (20) via a single communication channel (30), comprising the steps: - extracting a clock for the data exchange on the communication channel (30) from an external RF field (50); and - coding of the data via symbols, wherein the symbols comprise status information relating to simultaneous accesses of contactless card functionalities (21, 22, 23) on the transceiver (20) to the single communication channel (30).
