我的Nexus S，承上启下4和6 MIFARE的NFC标签，并希望具有NFC读/写acr122u设备（我还没有买它尚未）的桌面应用程序。

i have nexus s, nexus 4 and 6 mifare nfc tags, and want to make an desktop application with nfc reader/writer acr122u device (which i haven't bought it yet).

不过除了Android SDK中，是否有需要作出的桌面应用程序通过日食与Java一些其他的SDK？或者我可以直接购买并使用acr122u设备（不包括SDK），并通过蚀使应用程序？

But apart from android sdk, is there some other SDK needed for making an desktop application through eclipse with java? or i can directly buy and use the acr122u device (without sdk) and make the app through eclipse?

如果该SDK是必要的，没有任何链接，请免费下载或​​我必须从供应商本身？买吧

If the SDK is needed, is there any link to download it for free or i have to buy it from the vendor itself?

还有一件事，做的Nexus S和ACR122U支持FeliCa的NFC卡？ 我MIFARE经典NFC卡，其做工精细他们。

One more thing, does nexus S and ACR122U support felica nfc cards? I have mifare classic nfc cards, its working fine with them.

推荐答案

要开发应用程序的ACR122U你不需要从ACS购买SDK。从计算/发展的角度来看，ACR122U是一个智能卡读/写器。

To develop applications for the ACR122U you do not need to purchase the SDK from ACS. From a computing/development perspective, the ACR122U is a smartcard reader/writer.

要发展与Java中，你将需要 ACR122U司机并以$对 Java智能卡C $ C I / O API

To develop with Java you will need the ACR122U drivers and to code against the Java Smart Card I/O API

在要约ACS的SDK是一个简单的示例code为各种平台只是一个集合（Java，C＃.NET，VB6，C ++），它不要求与该设备相连接。

The SDK on offer from ACS is simply just a collection of sample code for various platforms (Java, C#.NET, VB6, C++) It is not a requirement to interface with the device.

Here是一些示例code这看起来可能对你有用。究竟是什么你想达到的。

Here is some sample code which looks like it could be useful to you. What exactly are you trying to achieve.

最后，如果你有兴趣在.NET开发再看看为.NET 的 CardWerk智能卡API。我用这个，它大大简化事情与winscard.dll seemeed想了很多的工作接口。

Finally, if you are interested in .NET dev then look at the CardWerk Smart Card API for .NET. I used this and it greatly simplified things as interfacing with winscard.dll seemeed like a lot of work.
