Abstract
It is provided a method implemented by an electronic device comprising a near field communication (NFC) system. The system comprises an NFC contactless front end, a plurality of secure element interfaces to which a plurality of secure elements are connected, and a processing unit adapted to control the NFC contactless front end and the plurality of secure elements through the secure element interfaces. The method comprises sending (S10) an initialization command to all the secure elements through the secure element interfaces, upon exposure of the NFC contactless front end to an NFC reader. The method improves the field of near field communication.
Claims10
A method implemented by an electronic device comprising a near field communication (NFC) system, wherein:
- the system comprises:
- an NFC contactless front end,
- a plurality of secure element interfaces to which a plurality of secure elements are connected, and
- a processing unit adapted to control the NFC contactless front end and the plurality of secure elements through the secure element interfaces,
- and the method comprises:
- sending an initialization command to all the secure elements through the secure element interfaces, upon exposure of the NFC contactless front end to an NFC reader.
An electronic device comprising a near field communication system, wherein the system comprises:
- an NFC contactless front end,
- a plurality of secure element interfaces adapted to connect a plurality of secure elements, and
- a processing unit adapted to control the NFC contactless front end and the plurality of secure elements through the secure element interfaces,
- wherein an initialization command is sent to all the secure elements through the secure element interfaces, upon exposure of the NFC contactless front end to an NFC reader.
A non-transitory computer program in a near field communication system, wherein the system comprises:
- an NFC contactless front end,
- a plurality of secure element interfaces adapted to connect a plurality of secure elements, and
- a processing unit adapted to control the NFC contactless front end and the plurality of secure elements through the secure element interfaces,
- wherein the non-transitory computer program comprises instructions for sending an initialization command to all the secure elements through the secure element interfaces, upon exposure of the NFC contactless front end to an NFC reader.
