UltraReset Android application

Hello,

Has anybody the android application to reset ultralight cards. From my vacation I still have 2 tickets from the Metro in Vancouver, would like to test against those cards.

Thanks

Re: UltraReset Android application

you could analyse the written data in the memory banks and compare with active tickets ...
there is no "reset a mifare ultralight", there are tons of diffrent systems with diffrent data layouts ...

Re: UltraReset Android application

Just install "MIFARE++ Ultralight" from the play store. It's easy to use and will do the job. But I can't guarantee you that it will work!

Chances are that you can reset them, as they're "normal" ultralights (not EV1s), and that the OTP is empty.
