So what let's just run through just a list of all the things you can hack with that one little device. All the radio things I just told you about, the RFID stuff, the NFC, which is the credit cards and more, infrared, which is TVs, projectors, and many other devices, GPIO, which is just anything that connects to the outside of this device so I can make devices work, and this would be the controller for it, iButton, which is a form of authentication that uses these things, these little metal prongs as a key, BadUSB, which emulates a keyboard, types like a couple thousand words a second, or I'm sorry, I meant it, I'm sorry, a thousand words, a couple thousand words a minute.
