Android App written in Kotlin made to fiddle with MiZip NFC tags.

Features :

• Read tag dump / create template
• Dump tag data
• Write a new tag
• Recharge a tag
• Change a tag's UID
• Reset a tag

Two options :

• You can either clone this repo, and build the app with Android Studio
• Or, you can download the .apk file in "Release", and install it manually

Start the app, put the tag on the back of your phone, and you're good to go

The tag's info should be displayed.

In case of the tag being repeatedly detected and disconnected, it is likely that you have some "exotic" access bits, if it is the case, feel free to send me your tag's dump so I can work on this issue.

Use the drop-down menu to select which dump file you want to read, then hit "Read" button, the dump's contents should be displayed

You can make a template (More on templates at the end of this Readme) out of the selected dump by touching the "Make template" button

It will read your Mizip tag's UID, generate all keys, and read all sectors, a dump should be saved in the Android/data/com.laen.miziptools/files/[UID].txt

If the app crashes when dumping, it's either you don't have a MiZip tag or some issue occured when writing the file (unlikely).

If it doesn't work, and you are sure your tag is a MiZip tag, feel free to submit an issue :)

Pretty straightforward, it will write content in your tag.

• UID : You can choose the UID, you can put X to have a random value
• Money : The amount you want
• Unique Key : To write a new tag, you need to have all of its keys (A AND B) to have the same value (this can be easily done with the "Reset tag" functionnality).
• Dump File : A template dump which will be modified with the new chosen UID, money and keys and written to the key

If it doesn't work, the most common issue is that your A and B keys are not the same

Easy, put amount of money you want (up to 655.3), tap recharge, and you're done ;)

UID : You can choose the UID, you can put X to have a random value

Be careful this action will erase everything on your tag. It could even erase all sectors 1-4 data even if you're not using a changeable block 0 tag.

It will write a predefined dump in your tag all data will be erased, and all A and B keys will be changed to "FFFFFFFFFFFF"

The key idea of this app is to allow the user to clone a MiZip tag in such a manner that it won't be detected.

To do this, you can make use of templates.

Templates are genuine tag dumps, but with some parts which are automatically modified by the "Create new tag" function (UID + BCC, money and Keys).

The modified parts are marked as X'es in the dump, these X'es are automatically added by the "Make template" button from the "Read dump" menu

The best way to use them is to dump a bunch of different keys (maybe 3 or 4), compare the dumps, find which parts of them are different (these parts could be used to identify you), modify them with random values, and then use this template to write new keys.

You can put "Y"es in the template where you want the "Write new tag function" to write a random value (You have to do it by yourself by editing the dump)

Unfortunately for you most of the code's comments and var/fun names are in French. If you have any questions and/or suggestions feel free to message me :)
