1. A method for managing application data in an NFC system embedded or to be embedded in a portable object and including a contactless data sending/receiving interface, one or more host processors, and a data routing or transferring processor to perform routing or transferring of application data between the contactless data sending/receiving interface and the one or more host processors, the method comprising:

  • generating complementary application data in response to the routing or transferring, within the NFC system, of external application data received or sent via the contactless data sending/receiving interface; and

    supplying the complementary application data to one of the one or more processors of the NFC system, wherein the complementary application data is generated in a predetermined format to simulate data read in or supplied by an external component via a contactless communication channel.
