Breaking into a Mifare Classic protected key vault that uses only anti collision as a security feature - no cryptography is used by that vault.



This device is obsolete - please use OpenPICC SnifferOnly 13.56MHz instead for sniffing

The OpenPICC project for Proximity Integrated Circuit Cards (PICC) is the counterpart to OpenPCD. It is a device that emulates 13.56MHz based RFID transponders / smartcards. OpenPICC can be used to e.g. simulate ISO 14443 or ISO 15693 transponders, such as those being used in biometric passports and FIFA worldcup tickets.

Like OpenPCD, the hardware design and software are available under Free Licenses.

Please refer our to our OpenPICC Development pages as well.

How to sniff RFID reader to ISO 14443 tag data transmission using OpenPICC

configure OpenPCD to send data continuously

  • connect USB debug cable to RS232_CMOS connector on OpenPCD - black wire is Pin 1
  • cu -l/dev/ttyUSB0 -s115200 (debug terminal - where ttyUSB0 is the debug cable. You can find 'cu' in the uucp packet. Make sure that your current user is also in the group 'uucp' to use this software )
  • power cycle OpenPCD again - OpenPCD boot message appear
  • press 'A' on debug terminal to enable continuous long packet transmission by OpenPCD - green LED turns on continuously in return

compile openpcd_test

Configure OpenPICC via USB debug cable

  • plug the debug cable into OpenPICC - black wire towards jumper socket in top right
  • press '}` several times to decrease the sampling clock divider to the lowest value
  • press 'd' till SSC-Mode is set to '5'
  • press 's' to start sampling
  • press 'a' to stop sampling
  • analyse /tmp/opcd_samples for sampled data (see example file)
