The fun part… you have to fix the card to the proxmark3 (duct tape) connected to a laptop and set the proxmark3 in sniff mode.If you have a y-usb cable, you can also power the proxmark3 with an usb power pack and connect it back to your desktop to get the traces.The best way to sniff all the transaction is to put the proxmark3 between the card and the reader.Push it against the reader, well aligned… and repeat it 3-4 times to get at least one good sniffed transaction.
