8. A method for handling operations associated with a plurality of applications in a Near Field Communication (NFC) device including an NFC Controller (NFCC), the method by the NFCC comprising:
storing, by the NFCC, a source host identity (ID), a destination host ID, a link ID, an application ID, a registration ID and a protocol ID associated with each application of one or more applications, wherein the registration ID is generated at the NFC device when at least one of the applications is stored in a removable element associated with the NFC device; and
managing, by the NFCC, the one or more applications simultaneously based on the source host ID, the destination host ID, the link ID, the application ID, the registration ID and the protocol ID stored in the NFCC,
wherein the one or more applications are stored in one or more hosts.
9. The method of claim 8 , wherein managing the one or more applications comprises sending data frames from the NFC device to a second NFC device based on at least one of the source host identity (ID), the destination host ID, the link ID, the application ID, the registration ID and the protocol ID stored in the NFCC.
10. The method of claim 8 , wherein managing the one or more applications comprises:
receiving data frames from a second NFC device; and
routing data frames in the NFC device based on at least one of the source host identity (ID), the destination host ID, the link ID, the application ID, the registration ID and the protocol ID stored in the NFCC.
11. A Near Field Communication Controller (NFCC) which is part of a Near Field Communication (NFC) device, the NFCC comprising:
a memory configured to store a source host identity (ID), a destination host ID, a link ID, an application ID, a registration ID and a protocol ID associated with each application of one or more applications, wherein the registration ID is generated at the NFC device when at least one of the applications is stored in a removable element associated with the NFC device; and
a processor configured to manage the one or more applications simultaneously based on the source host identity (ID), the destination host ID, the link ID, the application ID, the registration ID and the protocol ID stored in the memory,
wherein the one or more applications are stored in one or more hosts.
