Valid ISO14443A Tag Found - Quiting Search
=================================

for cloning it I used the command - script run mifare_autopwn
which return the error saying card cannot be detected. I tried raising the height but same result. Can someone help me with the command I can use to copy this type of key.

Thanks.

Re: how to Emulate MIFARE DESFire iso14443a type fob

1) what tags did you use to clone a mifare desfire card ?

2) Even given a correct blank magic uid card from my store, you probably need the 3des password to first extract the data and after which clone such a tag

3) i believe the mifare_autopwn is for mifare classic not the mifare desfire.

4) the height isn't the issue

I guess I will be the only one replying to this trend as your question is pretty wrong to start with.
