# RFID Radio-Frequency Identification (RFID) uses radio waves to read a small tag at a distance, without contact or line of sight. Passive tags have no battery — they are powered by the reader's signal — and cost cents, which is why they are everywhere: inventory and [[Supply Chain]] tracking, warehouse logistics, anti-theft tags, toll transponders, livestock and pet identification, passports, and access badges. [[Near-Field Communication]] is a short-range, secured descendant of RFID built for payments. ## Why it matters here RFID is the textbook case of a banal technology becoming a durable conspiracy anchor, which is exactly the kind of term-versus-thing split this lexicon exists to capture. **The mundane reality.** RFID is logistics infrastructure. Its real privacy issues are real but bounded: tags on purchased goods can sometimes be read after sale, and access badges or transponders create location records — the same ambient-tracking concern as other [[Sensor]]s, of interest to the [[Surveillance State]]. **The conspiracy life.** RFID is central to a long-running fear that governments or a coming world order will implant tracking microchips in people — fused in evangelical and prophecy circles with the biblical "mark of the beast" (Revelation 13), and revived during COVID-19 with claims that vaccines contained injectable RFID/microchips (they did not, and could not). Voluntary RFID/NFC implants do exist as a niche biohacking novelty, which conspiracy narratives cite as proof of feasibility while ignoring the gulf between an opt-in hobbyist chip and a covert mass-implantation program. The term's rhetorical work — collapsing a cheap inventory tag into an instrument of end-times surveillance — is what makes it a Terminology entry rather than just an engineering footnote. ## See Also - [[Near-Field Communication]] — the secured short-range descendant - [[Sensor]] · [[Surveillance State]] — the real (bounded) tracking concern - [[Supply Chain]] — RFID's actual dominant use
