The radio waves are generated
by the readers antenna.
A tag in the RF field uses energy from the radio
waves to respond to the readers commands

Radio Waves
Radio signals are electromagnetic waves, having a magnetic
component (H-Field) and an electric component (E-Field)
LF & HF systems use the Magneticfield to transfer power by
induction
Strength of this field falls off quickly
Liquids have less of an effect on H-Field
UHF systems use the Electricfield to transferpower by capacitive coupling
Strength of this field doesnt fall off as quickly
which provides potentially longer read distances
Liquids absorb E-field and reduce performance
Metals either shield signals or detune the inlays Special metal mount tags are typically required
ELECTRIC (E)FIELD
MAGNETIC (H)FIELD
