Abstract

PURPOSE: To write writing data in a non-contact state and to easily obtain a data card reduced in the effect on directionality by arranging a writing antenna so as to cross a reading antenna.
CONSTITUTION: A writing antenna 21 arranged so as to cross a reading antenna 22 and receiving the writing data signal W3 transmitted from a data writer/ reader 17 in a non-contact state and writing the writing data DATAIN detected from the writing data signal W3 on a data memory 11 is provided to a data card 20 having the reading antenna 22 modulating the amplitude of a response command signal W1 composed of a microwave as a carrier wave on the basis of the data stored in the data memory to return the signal W1. By this constitution, the data card 20 capable of writing the writing data DATAIN on the data memory 11 in a non-contact state and reduced in the effect on directionality due to the the mutual action of the writing antenna 21 and the reading antenna 22 can be realized.
