To use these keys with the libnfc MIFARE tools, they need to be in a MIFARE Dump format. Reading the data from a Skylanders NFC toy Those are the 16 keys A necessary to read or write the Skylanders NFC toy, generated algorithmically, instead of using an exploit. Generating the keys for a Skylanders NFC toy NFC device: SCM Micro / SC元711-NFC&RW openedĪn ATQA of 0f 01 with an SAK of 01 means an Activision Skylander NFC toy. (This is the same as for any MIFARE tag.) nfc-list Here's the output of the libnfc standard tool, nfc-list, when run against the "Ninjini" figure used in the demo. You may also want the emlinsert.py Python 2 program, which makes it easier to create the file necessary to write custom data to an NFC tag, listed at the bottom of this page. Download the eml2mfd.py and mfd2eml.py programs from the MIFARE Classic Tool source control so we can convert data back and forth. We'll be working in hexadecimal, which is easier for people to read, but the tools use the "MIFARE Dump" format. You'll need the tnp3xxx.py Python 2 program, which is an example implementation of the key generation algorithm, listed in New interoperability for Activision Skylanders NFC toys. You'll also need a libnfc-supported NFC reader.
Mac users may be able to use macports or homebrew, or compile it natively. (The last stable release of libnfc, 1.7.1, does not recognize the TNP3xxx tag inside Skylanders NFC toys as a MIFARE tag.) Linux users should be able to compile it using the normal process for their operating system. You'll need to compile libnfc's utilities from source. Consider writing your own data only to toys you no longer wish to use with the game.
