NFC MIFARE Classic Dumper

This application allows you to read and write MIFARE® classic tags with fast authentication, taking less than 1 second. Before writing, you can preview the data that will be added. You can also add different sets of keys and choose which one to use at any time. The dumps are automatically saved to your chosen directory every time you read the tag, unless you enable the "Just Read" option. You can choose to save the dumps in the same base directory or in their own UID sub-directory and/or KEY filename sub-directory, and you can change and combine these options at any time.

If you do not add a key set, the application will try to authenticate with the default "FFFFFFFFFFFF" key. It also has an automatic material day/night mode and supports Android versions from 5 to 16+.

Some frequently asked questions about this application include what card formats are supported, to which the answer is MIFARE® Classic 1K and any tag/card that can work in compatibility mode. Another question is why use this application instead of MIFARE Classic Tool to clone a tag or write a dump. The answer is that reading or writing a MIFARE® tag with 32 different keys is approximately 20 times faster with this application.

The key files used in this application need to be in a regular text file format (.txt) and should contain all 32 "A/B" keys in order, even if they repeat themselves. Each key should be on its own line, with the first 16 keys being "A" keys and the last 16 keys being "B" keys. An example of a key file for a MIFARE Classic 1K card is provided.
