I have been meaning to pick up a Proxmark3 for the last couple of months to round out my RFID testing kit (while waiting for the chameleon mini to be released this summer).

So of course I ordered and built one: 
Building it was fairly simple and Chris Merrett has an awesome github package put together to make installing it on OSX painless.
Once built and tested cloning HID Prox Cards (which open most corporate doors) is this easy:
I am really looking forward to getting this out into the wild and showing people why they shouldn’t trust their door locks at their business or in their hotel room.
