Nexus 的 NFC/RFID 入门
Nexus S NFC/RFID 入门。有人可以提供任何指导吗?
我有兴趣使用 Nexus 的 NFC/RFID 硬件创建一些自制演示。 我想我需要找到合适的标签以及如何将 url 编码为 Nexus 可以通过其标签应用程序读取的标签。 不确定 iso 14443 标签或 mifare 等
nexus 支持所有 libnfc 吗?
如果我root了设备,我可以访问写入功能吗?
谢谢
Getting started with Nexus S NFC/RFID. Can anyone provide any guidance?
I'm interested in creating some home brew demos using the nexus s NFC/RFID hardware.
I think I need to find the appropriate tags and how to encode urls into tags that the nexus s can read by it's tags app.
Not sure about iso 14443 tags or mifare etc
Does nexus s support all of libnfc?
If I root the device can I get access to write functionality?
Thanks

Nexus S 将读取 Mifare 标签。我已使用 Nexus S 从智能卡重播了 YouTube 视频 (http://www.youtube.com/watch?v=eu7fQsPjDls)。该 URL 是使用另一台设备 (Nokia 6212) 写入的。
The Nexus S will read Mifare tags. I have replayed YouTube videos (http://www.youtube.com/watch?v=eu7fQsPjDls) from a smartcard using the Nexus S. The URL was written with another device (Nokia 6212).
一种可能性:我注意到 Nexus S 可以读取 touchatag 制造的 RFID 标签,touchatag 是一家阿尔卡特朗讯合资企业,成立已有几年了。他们有一个网页(谷歌“touchatag store”),您可以在其中订购包含 10 个标签和 USB 读取器的“入门套件”。
这些标签被硬编码到 touchatag mothership 的 URL,www.ttag.be/[tagid]
因此,您可以通过他们的网站注册一个标签,在阅读器上扫描它,并将所需的 URL 与它相关联。当有人用手机读取标签时,它将显示为 www.ttag.be/[tagid] 并从那里重定向到所需的 URL。
One possibility: I've noticed that the Nexus S can read RFID tags made by touchatag, an Alcatel-Lucent venture that has been around a couple years. They have a web page (google 'touchatag store') where you can order a "starter kit" of 10 tags plus a USB reader.
The tags are hard-coded to URLs at the touchatag mothership, www.ttag.be/[tagid]
So the idea is you register a tag through their web site, scanning it on the reader and associating a desired URL with it. When someone reads the tag with their phone, it will show up as www.ttag.be/[tagid] and from there it redirects to the desired URL.
我在其中一个部分回答了这个问题Nexus S 相关问题。
此外,您还可以参考 developer.android.com URL 获取演示应用程序。我认为,这使用了虚拟 NFC 标签。
如果您有兴趣开发一些硬件演示,那么您需要购买一些实际的 NFC 标签,并在您的 Nexus S 手机设备上试用上述应用程序。我找到了一些网站 (1、2) 销售 NFC 标签、套件等。顺便说一句,我还没有尝试过这些网站。
基于 我遇到的,目前 Nexus S 只提供 NFC 标签的读取功能,并计划支持其他模式。
编辑:
Android 博客 指出以下是 Android 中的新功能2.3.3:
I had answered this question partially in one of the Nexus S related questions.
Also, you can refer the developer.android.com URL for a demo app. I think, this uses dummy NFC tag.
If you are interested in developing some hardware demos then you need to buy a few actual NFC tags and try out the above app on your Nexus S phone device. I found a few sites (1, 2) who sell NFC tags, kits, etc. BTW, I have not tried any of these sites.
Based on what I came across, for now Nexus S provides only read functionality for NFC tags and support for other modes is planned.
EDIT:
Android blog states following are the new features in Android 2.3.3:
我建议您使用像ACR122U-A2这样的读写器来读写标签Topaz和Mifare卡。
在 SmartId 中,我们是用这对双胞胎开发的一对解决方案。

I suggest you to but a reader/writer like ACR122U-A2 to read/write tag Topaz and Mifare Card.
In SmartId we are a pair of solution just developed with this twin.

如果您已将 Nexus 升级到 Android 4.0,那么您可能需要查看这个 Eclipse 插件< /a> (免责声明:自己项目的无耻插件)。它使用 Android NFC 硬件,还支持一些 NFC 读卡器,例如 ACR122U。
If you have upgraded your Nexus to Android 4.0 then you might want to check out this Eclipse plugin (disclamer: shameless plug of own project). It uses Android NFC hardware and also supports a few NFC readers like the ACR122U.
