System and method for parking detection and identification of moveable apparatus

A method for parking detection and identification of moveable apparatus, comprising following steps of: generating a magnetic field signal containing an identification code that can identify the moveable apparatus by a magnetic field generator disposed in the moveable apparatus; measuring magnetic field respectively by two magnetic field sensors of a magnetic field sensing apparatus disposed in a moveable-apparatus parking place or its peripheral area, wherein a first and a second magnetic field measurements are measured; and calculating a magnetic field measurement difference for obtaining the identification code, wherein the magnetic field measurement difference is (1) a magnitude of a difference of the first and the second magnetic field measurements, or (2) a magnitude of a difference of a magnetic field component of the first magnetic field measurement along a characteristic direction and a magnetic field component of the second magnetic field measurement along the characteristic direction.
