Abstract
A smart card may include: a support; and a magnetic field generator arranged on the support and including at least one track configured to generate a magnetic signal corresponding to a card information stored on the smart card by forming a magnetic field, wherein the at least one track may include a single magnetic cell in which both magnetic poles thereof are formed when an electric current flows therethrough, wherein the magnetic cell may include: a first layer having a first circuit pattern and a first via hole; a second layer having a second circuit pattern and a second via hole; and a core material provided between the first layer and the second layer, and wherein the first and second via holes are matched so that the electric current rotationally flows through the circuit patterns and the via holes in a predetermined direction with respect to the core material.
