wherein the method further comprises setting the first secure element and the one or more other secure elements to the normal working state when the identification information of the first secure element does not match the preset identification information and identification information of the one or more other secure elements does not match the preset identification information.

7. The method according to claim 6 , wherein the identification information comprises owner identification information that is used to identify a secure element issuer.

8. The method according to claim 6 , wherein the method further comprises:

when the identification information of the first secure element matches the preset identification information, configuring the routing information of the application installed on the first secure element into a routing table maintained by the processor.

9. The method according to claim 6 , wherein the setting the one or more other connected secure elements connected to the terminal to the non-normal working state comprises one or more of:

setting the one or more other secure elements to a disabled state;

setting a control switch on a control circuit that connects one of the secure element interfaces that receives one of the one or more other secure elements and the NFC controller to an open state; or

deleting, from a routing table of the NFC controller, routing information of an application installed on the one or more other secure elements.

10. The method according to claim 6 , wherein the method further comprises:

setting the one or more other secure elements to the normal working state when the identification information of the first secure element matches the preset identification information and the first secure element is removed from the terminal.
