This team is working day and night to turn your Chameleon Ultra into the device it was promised to be. I bought mine at DEFCON recently and was disappointed I couldn't really use it out of the box. I came across this app while searching through github and they saved my purchase. Although it's not close to 100% of all promised features, they are slowly getting there. Stick with this app and I'm sure you'll soon be able to use your Chameleon Ultra as it was meant to be.

This is the best little thing I have it saves me carrying about 12 different fobs for all the places i have to go in a day of work, The app is great to use, responsive and holds my less used cards and can transfer them easily when I do need them. I would love to see CLI in the future as a side option. I also await the application support of LF cards. Keep up the GREAT work guys

EM410X is only supported LF card type in firmware and we support reading it. Writing to T55XX isn't supported, but will be implemented in future. Thank you for your review 🦎
