Difference between Near and far field and Radio-frequency identification

Near and far field vs. Radio-frequency identification

The near field and far field are regions of the electromagnetic field (EM) around an object, such as a transmitting antenna, or the result of radiation scattering off an object. Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

Similarities between Near and far field and Radio-frequency identification

Near and far field and Radio-frequency identification have 6 things in common (in Unionpedia): Antenna (radio), Electromagnetic field, Microwave, Near-field communication, Radio frequency, Resonant inductive coupling.

Antenna (radio)

In radio, an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.

Near-field communication

Near-field communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm (1.6 in) of each other.

Radio frequency

Radio frequency (RF) refers to oscillatory change in voltage or current in a circuit, waveguide or transmission line in the range extending from around twenty thousand times per second to around three hundred billion times per second, roughly between the upper limit of audio and the lower limit of infrared.

Resonant inductive coupling

Resonant inductive coupling or magnetic phase synchronous coupling is a phenomenon with inductive coupling where the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates.
