Abstract

PURPOSE:To record auxiliary information without influence of an external magnetic force and to improve concealability of information by forming an information recorder of an unmagnetized magnetic material at least at a position not superposed with an IC of the surface or intermediate of a sheetlike medium. CONSTITUTION:This IC card 1 buries an IC 2 in a card base material, and main information is recorded in the IC 2. An oversheet 5 holds the base material in a sandwich state. An electrode 3 is formed on the surface of the oversheet 5 to connect the IC 2 to an external processor. In an information recorder 6, an unmagnetized magnetic material 4 is adhered to a part for avoiding the IC 2 on the surface of the oversheet 5, a code is formed, and auxiliary information is recorded. Since the IC 2 disturbs reading of the recorder 6 and is possibly damaged by the influence of a magnetic field at the time of reading, the recorder 6 is formed while avoiding the IC 2, and the electrode 3. Accordingly, possibility of no use of an IC card itself due to damage of the auxiliary information is prevented to improve its security.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an IC card, and particularly to an IC card useful as an ID card for storing personal information.

[Prior Art] Conventionally, an IC card 51 as shown in FIG. 4 is widely known.

This IC card 51 has a card base material 9 in which the IC 2 is embedded.
is sandwiched between oversheets 5, and a magnetic tape 52 is attached to the surface of the oversheet 5.

In this IC card 51, main information is recorded on the IC 2 and auxiliary information is recorded on the magnetic tape 52 to improve security.

[Problems to be Solved by the Invention] In the conventional IC card 51 shown in FIG. 4, information is recorded on the magnetic tape 52 by magnetization/non-magnetization.

Therefore, when the IC card 51 touches a permanent magnet or is placed on a television, it will be affected by external magnetic force.
Information on the magnetic tape 52 is easily destroyed.

Therefore, even though the IC 2 functions normally, there is a problem that the expensive IC card 51 becomes unusable due to the destruction of the information on the magnetic tape 52.

There is also the problem that the information on the magnetic tape 52 can be easily read using Magnepure or the like.

Therefore, an object of the present invention is to provide an IC card that allows auxiliary information to be recorded without being affected by external magnetic force and that improves the confidentiality of information.

[Means for Solving the Problems] The IC card of the present invention is an IC card in which an IC is mounted on a paper leaf-like medium, in which information is printed using an unmagnetized magnetic material on the surface or in the middle of the paper leaf-like medium, at least at a position that does not overlap with the IC. A structural feature is that a recording section is formed.

[Operation] In the IC card of the present invention, mutual influence with the IC is prevented by forming the information recording section at least in a position that does not overlap with the IC.

Next, by using an unmagnetized magnetic material in the information recording section, information is prevented from being destroyed by external magnetic force.

[Example] Hereinafter, the present invention will be explained in more detail with reference to Examples shown in the drawings. Note that this invention is not limited to this.

FIGS. 1(a) and 1(b) show an IC card 1 according to an embodiment of the present invention.

This IC card 1 has an IC 2 embedded in a card base material, and main information is recorded in the IC 2.

The oversheet 5 sandwiches the card base material from the front and back sides.

Electrode 3 is formed on the surface of oversheet 5 for connection between IC 2 and external processing equipment.

In the information recording section 6, the unmagnetized magnetic material 4 is attached to a portion of the surface of the oversheet 5 avoiding the IC 2, a code is formed, and auxiliary information is recorded.

As the magnetic material, one having a low coercive force such as pure iron, silicon steel, or soft iron ferrite can be used.

The information recording section 6 is formed avoiding the IC 2 and the electrodes 3 because the IC 2 interferes with the reading of the information recording section 6 and may be damaged by the influence of the magnetic field during reading.

The broken line indicates a scanning line for reading magnetic information, and the arrow indicates the scanning direction.

FIGS. 2(a) and 2(b) show an IC card 11 according to another embodiment of the present invention.

This IC card 11 is a non-contact type and does not have the electrode 3 in the IC card 1 described above, but instead has a transmitting device built into the IC 2 and an antenna core 7 buried in the card base material 9.
and an antenna 8, and outputs information to the outside by radio waves.

The auxiliary information is recorded in the information recording section 6 on which an unmagnetized magnetic material is attached to form a code, avoiding the IC 2 and further avoiding the magnetic antenna core 7.

FIG. 3 shows an IC card 2 according to still another embodiment of the present invention.
1.

An information recording section 6 formed of an unmagnetized magnetic material 4 is connected to an IC 2 embedded in a card base material 9 by a separation sheet 10.
and the antenna 8. 12
is a spacer sheet.

Note that if the IC card includes a built-in battery made of a magnetic material such as iron, this is also avoided when forming the information recording section.

[Effects of the Invention] According to the IC card of the present invention, the auxiliary information will not be destroyed by external magnetic force, nor will its contents be read by Magnepure or the like.

Therefore, it is prevented that the IC card itself becomes unusable due to destruction of the auxiliary information, and security is also improved.
