Patent ID: 8260199

Claim:
A method for storing and exchanging contactless data, comprising: providing at least one Near Field Communication (NFC) passive contactless integrated circuit in the form of a first semi-conductor chip, the passive contactless integrated circuit having a first contactless communication interface comprising a first antenna coil connected to the contactless integrated circuit; providing an NFC contactless reader in the form of a second semi-conductor chip, the reader having a second contactless communication interface comprising a second antenna coil connected to the contactless reader; providing a link circuit connected to the reader or integrated therein, the link circuit being different from the second contactless interface; providing a common portable support; gathering the contactless integrated circuit and the reader with the link circuit on or in the common portable support such that the first and second antenna coils are inductively coupled to one another to form an NFC functional module having both passive contactless integrated circuit functionality and reader functionality; using the contactless integrated circuit to store data and to exchange data with an external device, through the first contactless communication interface; using the reader to store data and to exchange data with an external device through the second contactless communication interface, including performing a sequence to set the contactless integrated circuit aside with respect to the data exchange with the external device; causing the contactless integrated circuit and the reader to exchange data through the first and second contactless communication interfaces and through the first and second antenna coils; causing the reader to exchange data with a master device via the link circuit, the master device being one of a mobile phone, earphones, PDA, game console, portable audio or video player, or a personal computer; and transferring to the master device, via the link circuit, data read in the contactless integrated circuit.
