blocks|key|887511|text|如果你的意思是让一个有电源的NFC设备伪装成一个被动设备(如标签)..不知道它有多好用，但安卓应用程序NFCClassic声称可以记录标签内容，然后允许标签被激活，并在近场通信阅读器中显示为复制的标签。创建录制的标签库。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|887512|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

If you mean getting a powered NFC device to pretend to be a passive one (eg a tag).. not sure how well it works but the android app NFCClassic purports to record tag contents and then allow the tag to be activated and appear to be the copied tag to NFC readers. Creates a library of recorded tags.

blocks|key|887559|text|对于NFC技术来说，这很容易。对于谷歌来说，它不会将其作为谷歌钱包来支持。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|887560|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

For NFC tech, it is easy. For Google, it will not support it as Google wallet.

blocks|key|670475|text|不，现在不是。Google在Google+IO+2011上指出，卡仿真不受支持，而且在一段时间内也不会支持。主要(且易于理解)问题:哪个应用程序应该在手机上获得模拟智能卡的权利？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|670476|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

No, not at the moment. Google pointed out at the Google IO 2011, that card emulation is not supported and won't be supported for a while. Main (and easy to understand) problem: Which App should get the right on the phone to emulate a smartcard?

blocks|key|670488|text|是的，看看NFCManager中的NDEF推送--使用Android4，你现在甚至可以创建NDEFMessage，在交互发生时推送到活动设备上。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|670489|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Yes, take a look at NDEF Push in NFCManager - with Android 4 you can now even create the NDEFMessage to push to the active device at the time the interaction takes place.

blocks|key|670506|text|你绝对可以使用点对点支持中的NDEFPush功能让Android手机写入标签阅读器，但你需要在标签阅读器端编写代码才能使用点对点(llcp)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|670507|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You can definitely make an Android phone write to a tag reader using the NDEFPush functionality in the peer-to-peer support - but you will need to write the code on the tag reader side to use peer-to-peer as well (llcp).

I've not verified that myself but it looks like people managed to include the hidden code into Android again.
They seem to be able to emulate a Mifare Classic card (iso-14443).
I'll soon test this myself, it looks very interesting.

If you want to do it for a commercial/free app you'll have a hard time, your users won't like to change their kernel to support your app.

Update:
There would be a simple trick to make your phone emulate a ticket: 
You can get a NFC-sticker and put it in or on the phone. This way you are able to read and write it at all times and other devices can also read and write it. 
It's just an idea I had, never seen that used anywhere of course ;)

Thank You!
Please mark my answer if it helps you!

From what I have understood so far, an NFC phone will act as an NFC reader which will read data from an NFC tag. Now my question is, can we switch this around? Can we make an Android NFC phone behave as the tag which an NFC reader will get data from?

Thanks for your assistance.

Can an Android NFC phone act as an NFC tag?

Android

据我目前所知，NFC手机将充当NFC阅读器，从NFC标签读取数据。现在我的问题是，我们能改变这一点吗？我们能让Android NFC手机充当NFC阅读器获取数据的标签吗？谢谢你的帮助。
