IC cards have appeared that allow data to be transferred from any terminal to the card, and which can be used on both sides.

A Non-contact transmission methods such as transmission using high frequency waves and transmission using a visiting method have been proposed. Some of these can be used for transmission from the terminal to the card, but cannot be used for transmission from the card to the terminal. This is because it requires a large amount of space and cannot be installed on a memory card that meets ISO standards, or requires a special signal shaper made of analog electronic components to convert the transmitted signal back to its original form. This is because you need it.

可能となった。[Effects of the Invention] The present invention is constructed as described above, and since control commands and data are transmitted and received between the terminal and the IC card in a non-contact manner, there is no need to form electrical contacts on the surface of the card, which eliminates the need to form electrical contacts on the card surface. The disadvantages of this method were that the contacts could become loose due to dirt on the card, the contacts would wear out, and the electronic components inside the card could be damaged due to static electricity.In addition, data could be exchanged even if the card was slightly oriented. In addition, with conventional contactless methods, the number of circuit parts increases and becomes complex, which tends to take up space on the card. However, since a magnetic route using Hall sensors and planar coils is used for transmission and reception, the transmission and reception section is easy to use. Furthermore, the Hall sensor and the planar coil can be configured concentrically, and the microprocessor, logic circuit, and memory including the Hall sensor can be integrated into one integrated circuit, making it even more compact. Since the signal is being received, there is no distortion ′+l
It can be converted to an L signal, does not require any analog electronic parts in the circuit (thus reducing the circuit operation power), and is extremely reliable, making it possible to exchange data between terminals and IC cards IHJ with a wide range of applications.
