Emulation uses native MIFARE DESFire command set. The DESFire protocol implemented here is [this reverse engineered version](https://github.com/revk/DESFireAES/blob/master/DESFire.pdf). 6 | 7 | [See the list of supported commands.](nfc/src/main/java/com/piotrekwitkowski/nfc/desfire/Commands.java) 8 | 9 | ## LibraryReader 10 | This module enables reading data from physical and emulated DESFire-based library ID cards. 11 | 12 | Its [programmed use-case](LibraryReader/src/main/java/com/piotrekwitkowski/libraryreader) is to 13 | 1. connect with a DESFire card (physical or with a specific Android application) 14 | 2. select a library DESFire Application 15 | 3. authenticate with AES key 16 | 4. read data from a DESFire File 17 | 18 | ## Configuration 19 | 20 | ### [HCE AID](https://developer.android.com/guide/topics/connectivity/nfc/hce#ManifestDeclaration) 21 | The "Android" AID used by both HCE and Reader Android applications can be configured in the [strings.xml](nfc/src/main/res/values/strings.xml) file of the nfc helper library. 22 | 23 | ### Emulated library ID 24 | The data (Application AID, AES key, Data Files) of the emulated DESFire Application can be configured [here](LibraryHCE/src/main/java/com/piotrekwitkowski/libraryhce/application). 25 | 26 | ### Library ID reader 27 | The data (Application AID and AES key) of the Reader module can be configured [here](LibraryReader/src/main/java/com/piotrekwitkowski/libraryreader/LibraryReader.java). 28 | 29 | ## Deployment 30 | To deploy the applications two NFC-capable Android phones are needed. My setup included motorola one (Emulator) and Nexus 4 (Reader). I have tested emulation with some Sony and Huawei phones and it didn't work so well. You can use [CTSVerifier](https://source.android.com/compatibility/cts/verifier) to test your phone's NFC capabilities. 31 | 32 | I was using Android Studio version 3.6.1. 33 | 34 | ## Issues 35 | Although I don't plan to update the app anytime soon, feel free to open Issues if you need clarification or help with NFC. I'd like to thank this way for many others that provided me with resources.
