A noncontact charger system is provided with a charger including a power transmitting planar coil that transmits high-frequency charging power, and a charged device including a power receiving planar coil which is magnetically coupled to the power transmitting planar coil to receive the high-frequency charging power in a state in which the power receiving planar coil opposes the power transmitting planar coil to form a predetermined gap, wherein the charger includes a primary authentication planar coil which transmits high-frequency authenticating power for authenticating the charged device and which receives a high-frequency authenticating signal for authenticating the charged device, the charged device includes a secondary authentication planar coil which is magnetically coupled to the primary authentication planar coil to receive the high-frequency authenticating power and output the high-frequency authenticating signal generated from the high-frequency authenticating power, to the primary authentication planar coil, and a space between the power transmitting planar coil and the power receiving planar coil overlaps with a space between the primary authentication planar coil and the secondary authentication planar coil. |
