Works like a charm!
No joke, I just full learned Mifare 1k security & protocols on 3 days with the help of MTools now I am about to purchase PN532 bluetooth to do more research about local transport security and public offices to expose vulnerabilities.
I know the developer and is very smart, the application is well written and the UI has become very beautiful with the latest updates. Best app on PlayStore to read and write your mifares.
As a researcher i found the tools productive and in working order. I recently updated my app amd lost my activation and Wilson was very helpful in resolving. If there are features that you think don’t work, i suggest you go on youtube for guides and tutorials how to use, or failing that Wilson can advise. This app has a very good reputation amongst security researchers amd developers.
