This is the official repository of ChameleonMini, a freely programmable, portable tool for NFC security analysis that can emulate and clone contactless cards, read RFID tags and sniff/log RF data. Thanks to over 1700 backers from our Kickstarter project, the current Revision G has been realized by Kasper & Oswald GmbH.

The ChameleonMini RevG is now also available via the Kasper & Oswald Webshop. Thank you for supporting the project!

We are aware of various third-party ChameleonMini clones or modified variants that are available on the Internet. Warning: We have evidence that some of these devices are defective or suffer from reading problems et cetera. Please understand that we cannot give support for these non-official devices, as we have no schematics / layout or other information, nor do we know the manufacturers. In case of problems, please contact the manufacturers of your device directly.

Note to the manufacturers: Some of the third-party ChameleonMini are violating the ChameleonMini license, please obey the license (see LICENSE.txt)!

To upgrade the firmware of your ChameleonMini, please visit the Getting Started page from the doxygen documentation.

If you have any questions, please visit the Issues page and ask your questions there so everyone benefits from the answer.

Please note that we cannot give any support if you have issues with the RevE-rebooted hardware or any GUI. Please use this issues page only for problems with the RevG hardware as distributed by Kasper & Oswald and for problems with the firmware from this page.

We appreciate every contribution to the project. Have a look at the External Contributions page.
