Abstract
In a non-contact IC (integrated circuit) module having an IC chip and a coil, the non-contact IC module communicates with a terminal via a booster unit. A communication system extends a communication distance of data modulated by using a carrier frequency (sub-carrier frequency). A communication auxiliary apparatus is used in a communication between a non-contact information medium and an external appliance.
