Abstract
A method for managing application data in an NFC system embedded or to be embedded in a portable object including a contactless data sending/receiving interface, one or more host processors and a data routing or transferring processor is described. The method includes generating complementary application data in response to the routing or transferring of external application data, and supplying the complementary application data to a host processor of the NFC system.
Claims17
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.
A device for managing application data integrated or to be integrated in a portable object, and provided to form with one or more host processors a communication system of NFC type embedded in the portable object, the device comprising:
- a contactless data sending/receiving interface of NFC type;
- and
- a data routing or transferring processor configured to perform routing or transferring of application data between the contactless data sending/receiving interface and the one or more host processors, the data routing or transferring processor being configured to:
- (a) generate complementary application data in response to the routing or transferring, within the NFC system, of external application data received or emitted via the contactless data sending/receiving interface, and
- (b) supply the complementary application data to one of the one or more host processors of the NFC system, wherein the data routing or transferring processor is further configured to generate the complementary application data in a predetermined format to simulate data read in or supplied by an external component via a contactless communication channel.

- 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 to form a command executable by the host processor to which the complementary application data is supplied.
