I want my android device to act as NFC tag. Is it possible to use NFC device as NFC tag? How can I achieve that? I have done read/write tag, beam data between devices. Michael Roland Depending on your NFC device, this may be possible. However, I do not agree with kamituel that this is being done by multiple applications through Android Beam. Android Beam uses NFC's peer-to-peer mode which (while it may have a similar effect) is not the same as using one device as a reader ( reader/writer mode ) and one device as a tag. Peer-to-peer mode uses a different protocol stack for communication than

I'm trying to test out the new Host Card Emulation features in KitKat, but the only KitKat device with NFC that I have at the moment is a 2012 Nexus 7. It does support card emulation through Google Wallet, and I can send and receive data to the two Master Card AIDs that it uses. However, when I try to implement my own HostApduService to handle communications with my own custom AID, Android doesn't route any APDUs to my service. I then tried to call CardEmulation.isDefaultServiceForAid to see if my service is the one that should handle my custom AIDs. When I include the CardEmulation class in

I have an Android tablet with Android 4.2. This tablet does not have NFC hardware. However I have an external USB reader: ACR 1252U , that came with an Android library . I have asked some general questions of my setup here . Now that it gets more specific, I need to ask another one. In this previous question I found out, that I can use the ACS Android library to access the readers card emulation capabilities. My first goal is to make that reader emulate an NFC tag, that contains a URL. Any NFC-capable Android phone should be able to scan this emulated tag and automatically open the browser. I

Please, I need any help to solve my problem. I can't exchange data normally between Android (4.4.2) phone and Arduino with NFC module, using HCE. I took example from Android samples, and slightly changed to return just IMEI number. public byte[] processCommandApdu(byte[] commandApdu, Bundle extras) { if (Arrays.equals(SELECT_APDU, commandApdu)) { String data = ((TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId(); return ConcatArrays(data.getBytes(), SELECT_OK_SW); } else { return UNKNOWN_CMD_SW; } } On Arduino side, my code is: void loop(){ Serial.println("Waiting for

I have developed a system that can read NFC tag using a reader with PN532 chip . It works ok. I can read Mifare Classic and Mifare Ultralight tag. Now I'd like to use a Nexus Tablet with Android 4.4.2 to emulate a tag. I have no experience with android development but I think it is possible. I have set NFC communication in the Nexus Tablet but I think I have to download or write some application to emulate a Tag and an NDEF communication. What is the easiest way? Michael Roland That depends on what Nexus tablet you have: Nexus 7 (first generation/2012 version): This device uses NXP's PN544 NFC

I am trying to build a communication between my Nexus4 HCE and Arduino PN532 Chip. on The Serial Monitor of Arduino,I could see some data transaction happening. But on ANdorid side, I get CET4T: Unsupported Class byte (0x60) CET4T: Unsupported Class byte (0xA0) BrcmNfcNfa﹕ UICC[0x0] is not activated Below is my apduservice.xml <host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android" android:description="@string/servicedesc" android:apduServiceBanner="@drawable/ic_launcher" android:requireDeviceUnlock="false" > <aid-group android:category="other" android:description="
