The Chameleon Mini is a hardware tool for NFC debugging, card emulation, security testing, reconnaissance, and general purpose debugging over this interface. These small card-sized NFC emulator devices are able to clone contact-less cards and RFID tags and sniff the raw RF-framed data sent over the interface without the overhead of Android's prohibitive NFC stack. This application is an interactive NFC debugging and logging tool for Android using the Chameleon Mini RevG (and RevE). It is attached to the Android device via a serial USB cable. Recent versions of the Chameleon boards (>= RevG) have the option to perform LIVE logging with the device where the raw logs are printed to the console in real time. This application provides a portable interface that is designed to be combined with the LOGMODE=LIVE logging features of the device for on the go and stealth NFC card reader debugging and testing.

The author thanks users, labs and Chameleon Mini device resalers who have donated time and hardware to helping me keep this CMLD application running at high quality. Donations of Chameleon Mini hardware have been made available to the developer of this application at free or reduced cost by the following contributors and third parties:

• The KAOS team (Kasper and Oswald) and original proprietors of the Chameleon RevG hardware / firmware sources (their retail site.
• The Lab401 team who have been primary merchants and supporters of the Chameleon Proxgrind RevG revisions (with Bluetooth) and the Tiny variations (their social media profile.
• Steve O'Shea (courtesy of Advanced Processing Systems Pte Ltd.) for providing recent bluetooth enabled devices for testing and ensuring forthcoming wireless connection support in the application.

The nice freeware icons used by the app were obtained from FlatIcon and their lovely sized transparent PNG enabled conversions of these images to many standard sizes. The GIMP image editor on Linux has also been used to create custom icons and colored logos for this application.
