Claim 18:
19. A smart card comprising:
a card body comprising a groove region and a connection pad;
a security chip disposed in the card body; and
a fingerprint sensor package configured to sense a fingerprint of a user and to transmit a signal related to a sensing result to the security chip,
wherein the fingerprint sensor package comprises:
a first substrate comprising a core insulating layer having a first surface and a second surface opposing each other, the first substrate further comprising a through-hole passing through the first surface and the second surface, a first bonding pad disposed on the second surface of the core insulating layer along a circumference of the through-hole, and an external connection pad disposed between an edge of the second surface of the core insulating layer and the first bonding pad;
a second substrate disposed in the through-hole of the core insulating layer, the second substrate comprising a plurality of first sensing patterns spaced apart from each other in a first direction, and extending in a second direction intersecting the first direction, a plurality of second sensing patterns spaced apart from each other in the second direction and extending in the first direction, and a second bonding pad;
a conductive wire connecting the first bonding pad and the second bonding pad;
a controller chip disposed on the second substrate; and
a molding layer disposed on the second surface of the core insulating layer, filling the through-hole, covering the second substrate and the first bonding pad, and spaced apart from the external connection pad, and

wherein the external connection pad of the first substrate is bonded to the connection pad of the card body.
