Questions: I have researched Mifare and other card emulation I have very good knowledge in programming (not Android, but C/C). I have proxmark and I have made multiple emulation codes for proxmark, so I know how the cards communicate. I don’t understand currently, does android enable full card emulation. I have researched this for about. Tunneling HTTP over NFC on Android using Host Card Emulation. Alex Suzuki Blocked Unblock Follow. An Android app that uses NFC with Host Card Emulation to perform bidirectional communication with an NFC reader application. In our case, the following output appears when holding the sample MIFARE tag included by Adafruit to the reader. Android 4.4 introduced host-based card emulation (HCE) but only down to the ISO14443-4 layer: Specifically, Android 4.4 supports emulating cards that are based on the NFC-Forum ISO-DEP specification (based on ISO/IEC 14443-4) and process Application Protocol Data Units (APDUs) as defined in the ISO/IEC 7816-4 specification.

There is NFC Card Emulator app, which is able to emulate NFC cards on Android. For Mifare cards it emulates card id. Is it possible to add the same feature to your app? |

Hi @and7ey, I've noticed this app too. However, I don't think I will add a feature like this. In order to emulate the UID ugly hacks are needed which work only on some Android devices and require root privileges. I think the app using this technique mentioned on stackoverflow. However, on my Nexus 7 (2012) for example, the app does not work. As far as I know, emulating more than the UID (the rest of the MIFARE Classic data) is even more complex. In theory it should be possible for most devices, but a custom build of the libnfc will be needed. |

Based on this article, i'm trying to emulate mifare card managing APDU on android.According to the APDU receive, my application should answer the right APDU, thus simulating the mifare behaviour.
with rfidiot.py, reading a mifare card give me :
With my app simulating the card i got a wrong comportment:
An error appear on FF B0 00 01 01 APDU command. And i don't know where the 6981 APDU command comes from.
Does someone can help me on this 'bug' ? Freneau the rising glory of america.

It is not possible what you are trying to do.. What @NikolayElenkov has done is emulate a ISO 7816-4 compliant card. MIFARE Classic is not ISO 7816-4 compliant (it does not use APDU commands and responses for communication). In fact, it is not even ISO 14443-4 compliant: it uses proprietary encryption on top of ISO 14443-3.
The fact that the communication looks like APDUs from the reader side, is because your reader strips off all encryption before it passes the data on and wraps that data inside 'virtual' APDUs. In that way, MIFARE cards can be used with software that can only deal with ISO 7816-4 compliant cards.
