本文深入探讨了Android平台下OpenNFC技术栈的优劣与使用方法，指出其作为非标准组件的特性及其对不同环境的适配性。强调了此技术栈在实现更多NFC功能方面的潜力，但同时也指出了由于其非内置性带来的安装与部署工作。建议开发者根据项目需求选择是否采用此技术栈，并概述了其与GoogleNFC堆栈之间的对比，最终得出结论，直到某手机制造商整合该技术栈，OpenNFC的吸引力有限。

At the moment (Android 2.3.4), the Android platform does not integrate the Open NFC stack. This stack has several advantages: not limited to one particular NFC hardware, portable to many different environments (not only Android), many additional features compared to the current stack. On the other hand, because Open NFC is not part of the standard Android environment, it requires some work (but it is actually quite easy) to use this stack in an Android platform. The Open NFC documentation describes this process.
The Open NFC stack is parallel activity and is optional replacement to the current stack. Due to its description it overcomes some limits of the Google NFC stack implementation and makes new HW adaptions (i.e. support for new tag types) easier…
This stack is intended to by used by device manufacturers, not mobile developers, because the standard Android kernel does not support modules loading, the Open NFC stack cannot be simply installed as another application, it requires a kernel change. But once the kernel is replaced, it is quite easy to deploy and use the Open NFC stack. An application developer should probably stick to the OS features, even if more limited, since they assure the portability of the code over any NFC-enabled phone. But if you are trying to use "more" features than what comes with Android, Open NFC is a good candidate.
In Conclusion : Until some phone manufacturer will integrate the stack into device, it does not make too much sense to be interested in Open NFC stack. An app developer cannot make use of Open NFC unless it is on hardware.
