I need to emulate a DESFire EV1 card on an Android device. However, I'm confused on how to use the Mifare SDK (lite or advanced) with the HCE. Is that even possible? I need to start the project and I had a lot of researches about how the data are stored and ciphered in the DESFire cards but I ended up with the fact that I need to use Mifare SDK on HCE. First of all, you cannot use the MIFARE SDK to emulate cards. The MIFARE SDK provides reader-side functionality only. Second, you cannot emulate the whole functionality of MIFARE DESFire (EV1) cards using Android HCE. However, you can emulate

I'm trying to emulate an NFC tag with my Nexus 5 according to this document , but my service is never invoke. Should I turn off Android beam? I'd like to emulate a simple tag containing a url. The reader is a Nexus 7 (2012) and I've figured out the process like a simple scan of a NFC tag using Android beam on Nexus 7. In addition I'm a bit confused about aid-filter name. Is there a list of them? I'm sure that I don't understand something. Thanks First of all (though this does not directly answer your question), the preferred way to transfer a URL between two Android NFC device is to use

I want to route APDUs I get from an NFC Reader to the SIM Card. According to the HCE documentation I thought it would be possible simply by creating an OffHostApduService with the according routing-entries (which I did). Sadly, the SIM does not seem to get any APDUs. SELECT-Commands that work when the SIM is directly attached to my workstation by a SIM-Reader return with 6a82 (File not found). In LogCat I found two interesting bits of information: Every time I shoot a select command which should be routed to the SIM, I get these entries: 01-14 10:44:18.501: D/BrcmNfcJni(1009): RoutingManager:

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. At this time, I would answer "no" or "with difficulty", but that could change over time as the android NFC API evolves. There are three modes of NFC interaction: Reader-Writer: The phone reads tags and writes to them. It's not emulating a card instead an NFC reader/writer device. Hence, you can't emulate a tag in this

This has been asked before with no responses, so I will try to phrase the question a bit differently. What are the various ways to pass some data to an Android Service without being able to bind to it or start it myself? Here's the issue - I have a HostApduService that is started by the operating system on every NFC card transaction. It requires the permission android.permission.BIND_NFC_SERVICE , which is a system permission, so my application can't bind to it. I don't want to leave data at rest so anything that gets written to the disk is a no-go. I thought of a few possible solutions, but

I have an Android app with a service registered to Android beam and a service registered to host card emulation. I want to decide when to enable/disable the HCE service in the code. The HCE service in the manifest looks like this - <service android:name="com.bimo.verifonewallet.service.MyHostApduService" android:exported="true" android:permission="android.permission.BIND_NFC_SERVICE" > <intent-filter> <action android:name="android.nfc.cardemulation.action.HOST_APDU_SERVICE" /> </intent-filter> <meta-data android:name="android.nfc.cardemulation.host_apdu_service" android:resource="@xml
