An CLI NFC application for reading, writing, analyzing, NFC ST SRI512 and SRIX4K tags.

• libnfc

You can use the provided build.sh or follow these simple steps:

mkdir build
cd build
cmake ..
make

• Read EEPROM content
• Read NFC Tag information (such UID, Serial number, System bloks etc...)
• Write EEPROM to a file
• Read EEPROM from a file
• Modify block manually
• Write EEPROM file to NFC tag
• Reset OTP bits

Usage: ./nfc-srix [-v] [-y] [-t x4k|512]

Options:
  -v           enable verbose - print debugging data
  -y           nswer YES to all questions
  -t x4k|512   select SRIX4K or SRI512 tag type [default: x4k]

• SRI512 - ISO14443B-2 ST SRx Tag IC 13.56MHz with 2 binary counters, 5 OTP blocks and anti-collision with 512-bit EEPROM in 16 Bloks
• SRIX4 - ISO14443B-2 ST SRx or ISO14443B-3 ST SRxTag IC 13.56MHz with 2 binary counters, 5 OTP blocks and anti-collision with 4096-bit EEPROM in 128 Blocks

Compliant ST SRx tags have some blocks that, once changed,cannot be changed back to their original value.Example Counters Blocks 5 and 6. Before writing a tag, make sure you're aware of this.
