For Anything: proxmarkii

`[..] Since then I have built a considerably more general device. My new device is capable of working with nearly any kind of 125 kHz card, and most types of 13.56 MHz cards. It is also capable of bidirectional communication, so that it can send data from the reader to the tag. This is necessary to work with most of the newer tags, including any cryptographic tag. (Note, of course, that a tag that uses cryptographic techniques can resist any practical attempts to clone it over the air; but I can still talk to the tag, and do anything that its reader could, even if I cannot clone the thing.)’
