That is correct. RFID chips respond to nearby RF through resonance in a microantenna which absorbs RF energy to power the activity. Previously, a glass-encapsulated silicon chip could be injected, for example into a pet. Now, it looks like nanotechnology is being used to put even smaller devices into people.
Yup, even RFID chips can be powered by external radio frequencies. Wha? You never read any Nikola Tesla mane?
