COMMUNICATION PROTOCOL BETWEEN A PROACTIVE SMART CARD AND ITS HOST TERMINAL

摘要

The invention concerns a communication protocol (PCINV) managing communication and data exchanges between an ISO 7816-3/4 compatible proactive smart card (CPA 10) and its host terminal (TAC 12) through a card reader (LEC 11), the PC-type terminal (TAC 12) being connected to an Internet-type or X25 external network by a network cable (53). The terminal (TAC 12) can also be connected with an auxiliary local reader. The communication protocol represented by the inventive communication layer integrates and extends the APDU proactive commands of the card reader of the proactive command protocol layer and the Event-type card Notification procedure on card reader, in particular for a proactive SIM card commands and procedure of the GSM 11.14/class a specification. Data transfers are managed by communication sessions on dynamically allocated data channels.
