My dump/key files are gone after updating MCT!
No. Read this: https://github.com/ikarus23/MifareClassicTool/issues/326

• Read MIFARE Classic tags
• Save and edit the tag data you read
• Write to MIFARE Classic tags (block-wise)
• Clone MIFARE Classic tags
(Write dump of a tag to another tag; write 'dump-wise')
• Key management based on dictionary-attack
(Write the keys you know in a file (dictionary).
MCT will try to authenticate with these
keys against all sectors and read as much as possible.)
• Format a tag back to the factory/delivery state
• Write the manufacturer block of special MIFARE Classic tags
• Create, edit and save key files (dictionaries)
• Decode & Encode MIFARE Classic Value Blocks
• Decode & Encode MIFARE Classic Access Conditions
• Compare dumps (Diff Tool)
• Display generic tag information
• Display the tag data as highlighted hex
• Display the tag data as 7-Bit US-ASCII
• Display the MIFARE Classic Access Conditions as a table
• Display MIFARE Classic Value Blocks as integer
• Calcualate the BCC
• Quick UID clone feature
• Import/export to common file types
• In-App (offline) help and information
• It's open source (GPLv3) ;)

Some important things are:
• The features this tool provides are very basic. There are no such
fancy things like saving a URL to an RFID-Tag with a nice looking
graphical user interface. If you want so save things on a tag,
you have to input the raw hexadecimal data.
• This App can NOT crack/hack
any MIFARE Classic keys. If you want to read/write an RFID-Tag, you
need keys for this specific tag first. For additional information
please read/see Getting Started from the links section.
• There will be no "brute-force" attack
capability in this application. It is way too slow due
to the protocol.
• The first block of the first sector of an original
MIFARE Classic tag is read-only i.e. not writable. But there
are special MIFARE Classic tags (aka magic tag gen2) that
support writing to the manufacturer block with a simple write command.
This App is able to write to such tags and can therefore create fully
correct clones. However, some special tags require a special command
to put them into the state where writing to the manufacturer
block is possible.
These tags will not work.
Remember this when you are shopping for special tags!
• This app will NOT work on some devices because
their hardware (NFC-controller) does not support MIFARE Classic
( https://github.com/ikarus23/MifareClassicTool/issues/1 ).
You can find a list of unsupported devices here:

This tool works very well. I have tried many different apps to achieve being able to read and write mifare rfid cards none work except this one. Just make sure you have the right type of magic card to clone onto. Very easy to use and reliable.

Excellent app indeed! The extended key set is extremely helpful. One glitch i faced when i tried to reimport the file generated by MCT sent myself through email. It imported successfully but couldnt open and gave error "some block contains error data (not hex)". Not sure how i can fix that. Works great on Nexus 7 Gen 1 with Android 4.4. Please add reader sniffing feature.

Had for a while and worked fine. Then all of a sudden it started opening by itself after every text I made. Wonder if it was taken over by a virus or something. Uninstalled. Response to developer's question: No NFC tags were near phone or in case. Opened by itself when I intentionally opened Chrome app. Then kept opening every few seconds, even after phone restart.

?!? Do you have a NFC tag close to your phone? Maybe in cover? MCT does automatically start, if a Tag was detected.
