I am trying to write on one of those cards, I got from eBay, advertised like that.
Both on Linux (Ubuntu 12.04 LTS) and on Windows 8 (pre-compiled client) it seems
like I can't select this "magic chinese" card. Any idea to point me to the right direction?
This is the version of the proxmark I am using:

Trying out the Proxmark Tool a little more on Windows, it gets slightly different error messages, still I can't figure out what's wrong

Try to put some distance (1cm) between antenna and tag.
