Abstract:
The present invention relates to a contactless communication method between an NFC card with a contact and contactless dual interface, installed in a communication terminal, and an external NFC device, the terminal including an NFC module coupled to the contact interface of the card and including a contactless communication interface, the method including the steps of: selecting one or the other of the contact and contactless interfaces of the card, transmitting signals between the card and the NFC device through the selected interface, and if the contact interface of the card is selected, through the contactless interface of the NFC module, and detecting by the card the presence of the NFC module connected to its contact interface, the selection of one or the other of the contact and contactless interfaces of the card being performed by the card depending on the result of the detection of the NFC module presence.
