问题描述
的Nexus S的装置NXP PN544 NFC控制器支持不仅SWP为UICC基于SE，而且S2C（又名NFC-WI）用于外部，例如micro SD卡SE。有谁知道这是如何启用，这意味着什么SD卡？这是不相关的谷歌Nexus S（有没有SD卡插槽），但NFC版的三星Galaxy S II已经配备了SD卡插槽，在这里，这将是一个问题。
the Nexus S device NXP PN544 NFC controller supports not only SWP for UICC based SE, but also the S2C (aka NFC-WI) for the external, e.g.micro SD card SE. Does anybody know how this can be enabled and what it means for the SD card? That is not relevant for the Google Nexus S (there is not SD card slot), but the NFC version of the Samsung Galaxy S II comes already with the SD card slot and here this will be a question.
我试图寻找这一点，即使是S2C的标准似乎是比较老的（我认为ECMA，2006年），我没有任何相关材料。这是什么意思支持S2C？该NXP544具有内置的支持，但对于手机？如果设备有一定的硬件支持一样，如在插槽和SD卡上的天线连接器可直接连接到RF接口
I have tried to search for that and even the S2C standard seems to be relatively old (I think ECMA, 2006) I did not any related materials.What it means supporting S2C? The NXP544 has the built-in support, but what about the phone? Should the device have some hardware support like, e.g. antenna connectors in the slot and on the SD card to be connected directly to the RF interface?

我们都有点失去了约NFC卡仿真Android中。谷歌和制造商正在有点太隐秘了。负责API的工程师们恕我直言玩smokescreen游戏。他们声称有关lack在卡仿真的兴趣，他们开发商可能面临困难，但事实是，他们希望保持黄金EGSS的母鸡了解自己暂时。
We are all a little bit lost about NFC Card Emulation in Android. Google and manufacturers are being a little bit too secretive about it. Engineers in charge of the API are IMHO playing a smokescreen game. They claim about the lack of interest in card emulation and they difficulties developers could face, but the fact is that they want to keep the hen of the golden egss for themselves for the time being.
没有人知道SWP SGII能力的事情。所有的传言。同样的情况与歌Nexus S，它面临着一些问题。显然，尽管应用程序可以访问嵌入式SE这将是毫无价值的，因为钥匙预计将保密由谷歌。走的唯一途径是希望的UICC和NFC控制器之间的SWP连接。从理论上来说是可能的，它理应由Madlmayr博士在去年MWC 的实例阐述。不过我有点怀疑他的成功同时考虑到，如果没有制造商的合作，关于SNS或SGSII基带固件支持，发送的APDU到UICC，是的，卡模拟通过UICC是一场失败的战争。
No one knows a thing about SGII SWP capabilities. All are rumors. The same happens with Nexus S, which faces several problems. Obviously though applications could access embedded SE it would be worthless, since keys are expected to be kept secret by Google. The only way to go is the hope in SWP connectivity between UICC and NFC controller. Theoretically it is possible, and it has supposedly demostrated by Dr. Madlmayr at last MWC. However I am a bit skeptical about his success taking into consideration that without the manufacturer's cooperation, regarding baseband firmware support on SNS or SGSII, sending APDUs to the UICC, that seems not yet supported, card emulation through UICC is a lost war.
