Method of communication between an NFC card dual interface contact and contactless NFC inserted into a terminal, and an NFC device

摘要

Procedure contactless communication between an NFC (NFSE) card dual interface contact (C6) and contactless (CLI), installed in a communication terminal (HD2), and an external NFC device (ED), the terminal comprising a NFC module (NFCC) coupled to the contact interface card and includes a communication interface contact (AC1), the method comprising the steps of: detecting by (NFSE) card presence NFC module (NFCC) connected to the contact interface (C6), selection by the card one or other of the contact interfaces and contactless card, depending on the result of detection of the presence of the NFC module and signal transmission between the card and the external NFC device via the selected interface, and if the contact interface card, the contactless interface (AC1) of the NFC module, wherein if the contact interface (6) is selected from is selected the (NFSE) card, the card retains activates its contactless interface (CLI) and listens to its contactless interface to receive and utilize a data exchanged between the NFC module terminal and the external NFC device (ED).
