Abstract
A near field communication (NFC) device for providing a communication path between a processing unit of the device and an external device is disclosed. A mobile device is also disclosed. An NFC integrated circuit (IC) is also disclosed. In an embodiment, an NFC IC includes a mobile host processor interface for communicating with a mobile host processor, a wireless interface for communicating with at least one of a contactless card and an external radio frequency (RF) reader, and a single wire protocol (SWP) interface for communicating with a secure element. In an embodiment, the NFC IC is configured to enable communications between the secure element and the mobile host processor by providing a channel for exchange of ISO 7816 commands between the mobile host processor and the secure element, wherein the ISO 7816 commands are carried over the SWP interface and the mobile host processor interface.
