A Novel Mobile Device NFC Stack Architecture

Mobile device manufacturers expect NFC stack to be operation system (OS) independent, hardware independent and OS application framework adaptive, but present mobile device NFC stacks can hardly meet all the requirements. By analyzing OS services, ETSI standards and NFC Forum standards, this paper propose a novel NFC stack architecture. In this architecture, NFC stack runtime environment encapsulates OS services related to NFC stack. NFC hardware abstract layer conceals the difference between different kinds of NFC controllers and offers abstract NFC hardware service. According to different NFC business scenario and NFC operating mode, NFC service model layer achieves the function defined by NFC Forum standards and constructs different service models. NFC service interface layer adapts to different OS application framework in order to facilitate NFC application development. The reference implementation of NFC stack based on this architecture can work on Android or Windows Phone and can adapt to corresponding application framework as well, it is also compatible with a variety of NFC controllers. Test result shows that mobile device with this NFC stack can meet NFC Forum Device Requirements 1.1.
