Re: New LF Tag

I dont know whether you had any luck after all with the tag.
I really hope you do because it is the SAME tag as the one I was referring to in my posting with subject "Unknown tag and it might be unique (!)" at:  http://proxmark.org/forum/viewtopic.php?id=6875

In my original posting I said that "The tags are extremely popular in the Mediterranean countries!  (see relevant photos; link below)".
Your "Gigieffe" tag is made by a defunct Italian company named "OTR". Please read my posting for more information
