I'm trying to do Host card emulation on an Android device using this example using ACR1281U NFC tag reader. This is the kind of application I want to make. As per the Android documentation and the example, it is required to register an AID in the Android project: <host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android" android:description="@string/servicedesc" android:requireDeviceUnlock="false"> <aid-group android:description="@string/aiddescription" android:category="other"> <aid-filter android:name="F0010203040506"/> <aid-filter android:name="F0394148148100"/> </aid

Is it possible for an Android application to send a previously stored RFID card ID to a NFC reader? The aim would be to use an Android device to enable access to a room instead of a physical RFID card. Having read a lot of other threads about NFC/RFID & card-emulation, I came to the conclusion it was not available for now in Android but I'm still kinda confused if it apply to this particular case. Can't the application simply send the card ID within a NDEF message or an APDU command or I'm just completely dreaming? Well, strictly speaking. For what you want to do you don't need card emulation.

I am often being asked about standards, the NFC is based on. I summarized my knowledge in the text below. I hope it can be an answer to such questions. Please feel free to correct it by posting comments and replies - I will include it into my text. Since NFC is based on RFID, it is often seen as RFID extension, its form or subset. It is correct because many existing standards from RFID were adopted in the NFC. The NFC base standard for physical layer is NFCIP-1 (ISO 18092 or ECMA 340) - it standardizes communication between two NFC devices. The RF layer use in the NFCIP-1 is directly inherited

maybe my question would be lost in the forum, but has somebody work with RFID tags? I know I can read them, but can I write or modify the inside data? Does anyone know where can I find more about this? RFID Standards: 125 Khz ( low-frequency ) tags are write-once/read-many, and usually only contain a small ( permanent ) unique identification number. 13.56 Mhz ( high-frequency ) tags are usually read/write, they can typically store about 1 to 2 kilbytes of data in addition to their preset ( permanent ) unique ID number. 860-960 Mhz ( ultra-high-frequency ) tags are typically read/write and can

My aim is to have only KEY A authentification and disable Key B (used space to store data). I read these documentations: http://www.nxp.com/documents/data_sheet/MF1S503x.pdf http://dangerousthings.com/wp-content/uploads/2012/08/NFC-Access-Control-for-Mifare-S50.pdf I understand how to calculate the hexadecimal values of these three bytes. But I don't understand how to choose the good data block and access byte rules : Data Block rule Here, I want to keep only key A (R & Write data) and deactivate Key B. I choosed the first rule: C1=0 C2= C3=0. Is this right? Access byte rule I would like to

The NFCEE_ADMIN permission is signature level. However, is it possible to "cheat" to get this permission on a rooted phone ? Maybe using a technique similar to the way ClockSync does it ? I am trying to use reflexion techniques to get access to NFCExtras : mAdapter = NfcAdapter.getDefaultAdapter(this); try { Class mynfcextras = Class.forName("android.nfc.INfcAdapterExtras"); Method getnfcExtras = mAdapter.getClass().getMethod("getNfcAdapterExtrasInterface"); Object nfcExtras = getnfcExtras.invoke(mAdapter); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } But

I have a problem regarding RFID card reader integration to a web page. I found out that the solution is to achieve this ActiveX component and java script. so, my question is that how can we build a ActiveX component for card reader and the java script Codeline to access this activex Component. Or if you can suggest an alternate way to integrate RFID reader to communicate directly with a web page, that would be great. SpringCard provides a technical guide and a live demo for developing a web page communicating with a PC/SC reader using Java applet. You will find it at the page, under Other
