RFID reader/duplicator

Anyone have any experience with these? I am looking to pick one up…

Preferably something that works with RF dump…

going scanning for credit card numbers?

Hmmm…

I have wanted one of these. They look fun and would be entertaining as hell

I heard Kevin Mitnick talking about these things on TwIT over the summer. They are pretty neat. Lots of people are using them to duplicate those HID employee badge cards.

My work uses them, as does a shitload of other places.

I am doing more research trying to find the most compatible with current software offerings…
