The type of coupling used, inductive or backscatter (also known as radiative), depends on the frequency and the distance between the tag and the interrogator antenna. Inductive coupling uses near-field effects, while backscatter coupling uses far-field effects. How are passive RFID tags actually powered by an RFID reader?

Inductive coupling is seen in LF, HF, and UHF applications that include coils/antennas in the tag infrastructure. Increasing the amount of loops of wire (coils) in a tag that uses inductive coupling increases the amount of current that would be generated in the tag.
Coupling allows the reader to recognize and retrieve information from the tag. Inductive and radiative coupling are the two primary types of coupling in an RFID system. Whether inductive or radiative coupling is used typically depends on the frequency level of the tag. TagMii is based on two important facts and observations from practical RFID communication: inductive coupling and channel similarity. If two tags are put in physical proximity, they will interfere with each other and cause changes on their backscatter signals. This phenomenon is called inductive coupling [6, 7].

work on two distinct principles: “inductive coupling in the electromagnetic near-field with load modulation at LF/HF” or “wave coupling in the electromagnetic far-field with backscatter at UHF/MW”.
The transfer of energy and data in smart label applications is based on vicinity inductive coupling. Inductive coupling is a means of conveying radio frequency energy via an oscillatory high-frequency (HF) magnetic field. In near-field inductive coupling, the reader antenna loop and the tag coil windingsThere are two ways of communication or «coupling» used in RFID systems; inductive coupling and capacitive coupling. Inductive coupling: Inductive coupling is the mode of operation at the HF frequency and consists of the emission of a magnetic field by the reader.Inductive coupling is used by low-frequency or high-frequency RFID systems. This way the tag and the reader can use a loop-style coil for an antenna because the traditional antenna would need to be too long due to the long wavelengths of the low-frequency waves.
In technical terms, inductive coupling is the transfer of energy from one circuit to another by virtue of the mutual inductance between the circuits. In an RFID system that uses inductive coupling, the reader antenna and the tag antenna each have a coil, which together form a magnetic field.
