This video demonstrates Josh Universe unlocking Windows 10 utilizing a NFC implant. NFC stands for Near-Field Communication and is a subset of RFID(Radio Frequency Identification). NFC works by sending very small radio waves to a NFC reader which reads those waves and interprets them into data which can be used for any various purposes. No batteries or other power sources are needed since the NFC reader sends a minuscule amount of electromagnetic power. Technologies like GPS, WiFi, etc cannot be utilized with NFC as information can only be exchanged when a NFC tag is powered, that is only a few centimeters!
