people keep asking what the orange dolphin actually does.
it is not a magic key.
it is a handful of radios that were always there: sub-ghz, 125 khz rfid, 13.56 mhz nfc, infrared, gpio, ibutton: collected into one pocket-sized box with a menu.
that is the entire trick.
the device was never the interesting part. the interesting part is how much of the world is still built on the assumption that nobody would bother to look.
