How to read passive RFID cards using Android?
提问by Siddhesh
I am working on Android application (Droid Incredible).
我正在开发 Android 应用程序（Droid Incredible）。
I am planning to read passive RFID tags using Android phone but I found that there is no slot for Android to connect to RFID reader.
我打算使用 Android 手机读取无源 RFID 标签，但我发现 Android 没有插槽可以连接到 RFID 阅读器。
After some research, I found out that I will have to get RFID reader which can send RF data over bluetooth to Android. But I am not sure which company manufactures it or what will be cost of such RFID reader.
经过一番研究，我发现我必须获得 RFID 阅读器，它可以通过蓝牙将 RF 数据发送到 Android。但我不确定哪家公司制造它或这种 RFID 阅读器的成本是多少。
Is there any one who can help me or throw some light on this issue?
有没有人可以帮助我或解决这个问题？
Thanks Siddhesh
谢谢 Siddhesh

Inorder to read RFID Passive tags using Android devices, Now there are Android devices with RFID integrated in it to read the Passive tags and you can customize your android application according to your requirement
为了使用Android设备读取RFID无源标签，现在有集成RFID的Android设备来读取无源标签，您可以根据您的要求定制您的Android应用程序
If you want to build your own circuit for reading Passive tags and to get the tag data to your Android device, The best way is to use Arduino Microcontroller Boards. Using EM-18 and RC- 522 RFIDmodules integrated with Arduino, you can read the LF and HF Passive tagsrespectively. If tag reads, you can get the data either in serial monitor or display attached to the Arduino. To get this RFID tag data to the Android device, the circuit which helps you is HC-05 Bluetooth Module which sends/receive to/from Android device.
如果您想构建自己的电路来读取无源标签并将标签数据发送到您的 Android 设备，最好的方法是使用 Arduino 微控制器板。使用与Arduino集成的EM-18和RC-522 RFID模块，您可以分别读取LF和HF无源标签。如果标签读取，您可以在串行监视器或连接到 Arduino 的显示器中获取数据。要将这个 RFID 标签数据发送到 Android 设备，可以帮助您的电路是 HC-05 蓝牙模块，它向/从 Android 设备发送/接收。

悉达什：
RFID is supported since Android 2.3 (GingerBread) but with an exception (if the brand handset has available the hardware to do that). On the most of the cases you can check on handset's cover a label like as NFC and so on.
从 Android 2.3 (GingerBread) 开始支持 RFID，但有一个例外（如果品牌手机有可用的硬件来做到这一点）。在大多数情况下，您可以检查手机外壳上的标签，例如 NFC 等。
I understand is established by RF (HF) and its purpose is to replace: bar codes, QR codes and bluetooth and it looks like that is not too fast to permit a big amount of transfer information.
据我所知，它是由 RF (HF) 建立的，其目的是替代：条形码、二维码和蓝牙，而且速度似乎不太快，无法传输大量信息。
is there any other tips related to implement class and objects to perform on Eclipse Proyect, I will Thank You.
是否有任何其他与在 Eclipse Proyect 上执行的类和对象相关的提示，我会谢谢你。
