MIFARE++ Ultralight

About MIFARE++ Ultralight Android App

MIFARE++ Ultralight is a tool to read, write, clone, edit all types of MIFARE Ultralight® tag variants, as well as transfer their contents among Android devices and computers in simple TXT format encoded in hexadecimal.

SUPPORTED TAG TYPES:
- MIFARE Ultralight (MF0ICU1)
- MIFARE Ultralight C (MF0ICU2)
- MIFARE Ultralight EV1 (MF0UL11)
- MIFARE Ultralight EV1 (MF0UL21)
- NTAG203 (NT2H0301)
- NTAG213 (NT2H1311)
- NTAG215 (NT2H1511)
- NTAG216 (NT2H1611)
- MIFARE Ultralight emulators

SUPPORTED FEATURES:
- Reading and writing of the entire tag is done in one-shot
- Efficient writing of different pages only
- Saving and loading content from TXT files anywhere in the file structure where the OS has permissions
- On standard tags, reading and writing is only limited by tag security restrictions (see tag datasheets)
- On emulators, if security restrictions allow, the following features are additionally supported:
- Writing UID in pages 0, 1, 2
- Writing manufacturer reserved byte 1 in page 2
- Resetting OTP and lock bits
- Writing one-way counters
- Reading 3DES key fields
- Reading and writing tags with manufacturer IDs (UID0) other than 0x04
- Reading and writing tags with non-standard number of pages up to 256

LIMITATIONS OF THE INITIAL VERSION (planned as TODO list):
- No auto-correction of UID checksum bytes
- may result in a bricked emulator (failure to pass the next anticollision procedure) if no auto-correct is implemented on emulator side
- Saved TXT files have UNIX newline characters 0x0A, because Android is UNIX-based
- Windows still has applications to work with such files: Wordpad, Notepad++, etc.
- Tags compliant to ISO 14443-A and MIFARE command set, but with non-standard ATQA and SAK values, are not supported
- Every other (security) feature or command other than READ and WRITE is not supported
