1. An RFID tag comprising:
a conductor having a planar surface; and
an RFID module configured to be electromagnetically coupled to the conductor, such that the RFID module is entirely overlapped by at least a portion of the planar surface of the conductor when viewed in a direction normal to the planar surface of the conductor, the RFID module including:
an RFIC configured to receive power induced by receiving an electromagnetic wave for power reception to output a transmission signal;
a power reception coupling unit configured to electromagnetically couple to the conductor to receive the power; and
a transmission coupling unit configured to electromagnetically couple to the conductor to output the transmission signal to the conductor,
wherein either the power reception coupling unit or the transmission coupling unit includes a planar conductor configured to electrically couple to the conductor.
