TonUINO NFC Tools

Android app to write and read NFC tags that can be used on the TonUINO DIY music box.

For discussion, see this thread (in German), or use github issues.

The app is available for download on github, installable using the Google Play Store or the F-Droid Store.

The github releases are built on CircleCI .
Google Play releases are built using fastlane.

• Get BytesFormatter to work without issues
• Hide on-screen-keyboard when switching between edit fragments
• Allow users to write a note or title to the NFC tag
• Allow users to keep a list of tags
• Simulate NFC tag
• Use proper Material design theming instead of faking it
  • MainActivity if NFC is not available

#	name	range	description
0	cookie	uint32	identifies TonUINO, expected 0x1337b347
4	version	uint8	always 1
5	folder	uint8	values between 1 and 99, see dfplayer docs
6	mode	uint8	values between 1 and 5, see next table
7	special	uint8

Different Modes
Based on the value of byte mode and what happens, when the next and previous buttons are pressed

#	title	description	next	previous
1	Hörspiel audio book (single file)	plays a single file in the folder	stop	Start title again from the beginning
2	Album	play every file in the folder	next file	previous file
3	Party	play files in the folder in random order	play random file	start title again from the beginning
4	Einzel single	play a single file in the folder	stop	start title again from the beginning
5	Hörbuch audio book (multiple files)	play all files in the folder and keep track of the progress (will start at the last file the next time	next file	previous file
6	Admin	Not functionality	—	—

Special
Is only used in specific modes to specify variables:

• mode 4: file number
• mode 6: placeholder, no functionaliy yet

#	name	range	description
0	cookie	uint32	Identifies a Tonuino tag, usually 0x1337b347
4	version	uint8	always 2
5	folder	uint8	Values from 1 to 99, see dfplayer docs
6	mode	uint8	Values from 1 to 5, see next table
7	special	uint8
8	special2	uint8

Different Modes
It supports all modes of TonUINO 2.0 and adds these

#	title	description	next	previous
7	Von-Bis Hörspiel	play a random file from the folder between special and special2	stop	start title again from the beginning
8	Von-Bis Album	play all files between special and special2	next file	start title again from the beginning
9	Von-Bis Party	play all files between special and special2 in random order	random file	start title again from the beginning

Modifier Tags (aka admin tags)

All have a folder value of 0

Modifier	byte 6	byte 7	Description
SleepTimer	1	Play duration in minutes (255 max)	Pauses playback after timer
FreezeDance	2	—	Randomly pauses the track after 5 to 30 seconds
Locked	3	—	All buttons are locked and no new card will be read
ToddlerMode	4	—	All buttons are locked
KindergartenMode	5	—	Previous and back buttons are locked. Adding a new card will not stop the current track but will schedule it as next track
RepeatSingleModifier	6	—	Repeat current track
FeedbackModifier	7	—	Will e.g. tell volume before changing it

NFC Host Card Emulation

It would be great if the app also can act as an NFC tag to simulate TonUINO tags, some links to this: Official Android docs

Here is a very good example https://github.com/grundid/host-card-emulation-sample which will write to you «Hello Desktop!» The App emulates a MIFARE card with this AID 0xF0, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06 You should make your self familiar with the HCE code.

In the other side you should have an NFC reader (in your case MIFARE NFC) which will be looking for the same AID as in the HCE App. Normally you should send this cmd to the Android phone from your reader after you have brought the two devices close enough 0x00 [CLA], 0xA4 [INS], 0x04, 0x00, 0x07 [Lc], 0xF0, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x00 [Le]

NFC tag type support

Currently only Mifare Classic and Ultralight are supported, but in case generic NfcA support is wished, start with these links:

Android app to write NFC tags for the TonUINO diy music box

Nfc tools github android

NFCGate is an Android application meant to capture, analyze, or modify NFC traffic. It can be used as a researching tool to reverse engineer protocols or assess the security of protocols against traffic modifications.

This application was developed for security research purposes by students of the Secure Mobile Networking Lab at TU Darmstadt. Please do not use this application for malicious purposes.

• On-device capture: Captures NFC traffic sent and received by other applications running on the device.
• Relay: Relays NFC traffic between two devices using a server. One device operates as a «reader» reading an NFC tag, the other device emulates an NFC tag using the Host Card Emulation (HCE).
• Replay: Replays previously captured NFC traffic in either «reader» or «tag» mode.
• Clone: Clones the initial tag information (e.g. ID).
• pcapng export of captured NFC traffic, readable by Wireshark.

Requirements for specific modes

• NFC support
• Android 4.4+ (API level 19+)
• EdXposed or Xposed: On-device capture, relay tag mode, replay tag mode, clone mode.
• ARMv8-A, ARMv7: Relay tag mode, replay tag mode, clone mode.
• HCE: Relay tag mode, replay tag mode, clone mode.

1. Initialize submodules: git submodule update —init
2. Build using Android Studio or Gradle

As instructions differ per mode, each mode is described in detail in its own document in doc/mode/ :

Captured traffic can be exported in or imported from the pcapng file format. For example, Wireshark can be used to further analyze NFC traffic. A detailed description of the import and export functionality is documented in doc/pcapng.md.

NFCGate provides an in-app status check. For further notes on compatibility see the compatibility document.

Known Issues and Caveats

Please consider the following issues and caveats before using the application (and especially before filing a bug report).

When using modes, that utilize HCE, the phone has to implement the NFC Controller Interface (NCI) specification. Most of the phones should implement this specification when offering HCE support.

Confidentiality of Data Channel (relay)

Right now, all data in relay mode is sent unencrypted over the network. We may or may not get around to implementing cryptographic protection, but for now, consider everything you send over the network to be readable by anyone interested, unless you use extra protection like VPNs. Keep that in mind while performing your own tests.

Compatibility with Cards (relay, replay, clone)

We can only proxy tags supported by Android. For example, Android no longer offers support for MiFare classic chips, so these cards are not supported. When in doubt, use an application like NFC Tag info to find out if your tag is compatible. Also, at the moment, every tag technology supported by Android’s HCE is supported (A, B, F), however NFC-B and NFC-F remain untested. NFC-A tags are the most common tags (for example, both the MiFare DESFire and specialized chips like the ones in electronic passports use NFC-A), but you may experience problems if you use other tags.

Compatibility with readers (relay)

This application only works with readers which do not implement additional security measures. One security measure which will prevent our application from working in relay mode is when the reader checks the time it takes the card to respond (or, to use the more general case, if the reader implements «distance bounding»). The network transmission adds a noticeable delay to any transaction, so any secure reader will not accept our proxied replies.
This does not affect other operating modes.

Android NFC limitations (relay, replay)

Some features of NFC are not supported by Android and thus cannot be used with our application. We have experienced cases where the NFC field generated by the phone was not strong enough to properly power more advanced features of some NFC chips (e.g. cryptographic operations). Keep this in mind if you are testing chips we have not experimented with.

Publications and Media

An early version of this application was presented at WiSec 2015. The extended Abstract and poster can be found on the website of one of the authors. It was also presented in a brief Lightning Talk at the Chaos Communication Camp 2015.

External NFC Service (native style) for Android

Library for interaction with ACS NFC readers over USB; external NFC support Android devices.

• External NFC reader management and interaction
• Parallell use of external and/or internal NFC (i.e. in the same activity, both enabled at the same time)
• Support for both tags and Android devices (Host Card Emulation), simultaneously
• Use of forked android.nfc classes (Ndef, MifareUltralight, IsoDep, etc) for Android 10+ support.

As this project very much simplifies implementation for use-cases requiring external NFC readers, it saves a lot of development time (2-8 weeks depending on use-case and previous knowledge).

Bugs, feature suggestions and help requests can be filed with the issue-tracker. DO NOT send me emails unless you’re prepared to pay for my time.

This repository contains source code for

There is also a Host Card Emulation client app for use with the Basic client app as well as Android-to-Android communication.

External NFC reader API

The API defines

• broadcast actions
  • service start / stop and status
  • reader open / close and status
  • tag connect / disconnect
• extras objects for interaction with readers
  • disable beeps
  • display text
  • configure NFC tech types (PICC)
  • enable/disable LEDs
  • run custom commands
  • and more..
• abstract activities for interaction with built-in and external NFC (simultaneously)
• these currently depend on the NDEF Tools for Android project.
• Programmatically start and stop the service (see methods startService() and stopService() in the NfcExternalDetectorActivity class in for an example).

Currently the ACS readers

are supported and must be connected to your Android device via an On-The-Go (OTG) USB cable.

Additional ACR readers might work depending on their command set, however custom reader commands will (like LED, beep etc) will not be available.

Supported tag technology

The following tags are supported by the service

• Mifare Ultralight familiy
  • Mifare Ultralight
  • NTAG 21x with FAST READ
• Mifare Classic and friends
  • Not recommended due to security and compatibility issues
• Desfire EV1 tags
• Host Card Emulation — interaction with Android devices.

The readers can for the most part can be enabled for all tag types at the same time, including Host Card Emulation.

• Some readers only support a subset of the above tags
• For ACR 122U the Mifare Classic does not work well.
• No built-in NDEF support for Desfire EV1 cards

• assume all NTAG21x Mifare Ultralight targets. This improves read speed, particullary for the tags which have legacy equivalents, like NTAG 210 and 213
• read only tag UIDs, ignore other tag data. This improves read speed.
• read NDEF data automatically
• read UID for Desfire EV1 targets automatically

Note that not all Android devices actually have an USB hub, in which case no USB devices work.

Does the ACR reader not light up when connected to your device, even after the service asks for USB permissions? The ACR reader shuts down if there is not enough battery, so try charging your battery more, or connect external power.

If you are using external power, be aware that the connection order (device, reader, power) might be important. Known symptom:

• Seeing an USB permissions window that disappears rather quickly.

There is quite a few types of tags out there, and if your tag type is not recognized, please let me know. If the tag does not register at all, make sure that auto polling is configured, and that the right protocols are enabled. Use the below utility apps for tweaking your reader settings.
