This app allows to clone/create the Mifare(R) Ultralight EV1 NFC tag that are necessary for Bonaverde Berlin raosting/grindind/brewing machine to work after manufacturer's insolvency. Special thanks to the dedicated Facebook group and especially Hackaverde, Craig Whyte and Michael Grundler who deliverred importing information without this app wouldn't be possible.
This app can be compiled by Visual Studio 2019 with installed Xamarin for Android/iOS feature set.
Feel free to fork, change and send PR to me. The android and iPhone versions are available through Google Play Store or Apple AppStore.
You can either read an existing tag and write it to any tag having still OTP != FFFFFFFF or read it from a file. The file data format is very simple and can be produced by the Android app "Mifare++ Ultra". By using "speaking" names thus you have a simple browser to a tag library. Example:
filterreset
