IC card, IC card manufacturing method, IC card manufacturing apparatus and IC card judgement system
View Patent ↗An IC card comprising: an IC module including an IC-chip in which intrinsic information is stored at the stage of card manufacturing or card issuing and an antenna supported by an antenna supporting member; and two base plates between which the IC module incorporated with an adhesive layer; wherein hidden intrinsic information corresponding to the stored intrinsic information is recorded on a part of the antenna supporting member in such a way that the hidden intrinsic information is invisible by reflection light from the surface of the IC card and is read out from transmission light due to a transmission density difference between the recorded part of the hidden intrinsic information and a non-recorded part.
1. An IC card comprising:
an IC module including an IC-chip in which intrinsic information is stored at the stage of card manufacturing or card issuing and an antenna supported by an antenna supporting member; and
two base plates between which the IC module incorporated with an adhesive layer;
wherein hidden intrinsic information corresponding to the stored intrinsic information is recorded on a part of the antenna supporting member in such a way that the hidden intrinsic information is invisible by reflection light from the surface of the IC card and is read out from transmission light due to a transmission density difference between the recorded part of the hidden intrinsic information and a non-recorded part.
2. The IC card of claim 1 , wherein said hidden intrinsic information has absorption in a visible light region and is readable based on a transmission density difference between the recorded part of the hidden intrinsic information and a non-recorded part in the region.
3. The IC card of claim 1 , wherein said hidden intrinsic information is provided by use of an infrared absorbing material which is invisible in a visible light region and is read out based on transmission density difference between the recorded part of the hidden intrinsic information and a non-recorded part in an infrared wavelength region.
4. The IC card of claim 1 , wherein said hidden intrinsic information comprising at least one of information of an intrinsic card number and information of personal certification.
5. The IC card of claim 4 , further comprising:
an image receiving layer provided on one of said two base plates; and
a writing layer provided on the other base plate;
wherein the information of personal certification including a name and a face image is recorded on the image receiving layer.
6. An IC card comprising:
an IC module including an IC-chip in which intrinsic information is stored at the stage of card manufacturing or card issuing and an antenna; and
two base plates between which the IC module is incorporated with an adhesive layer;
wherein hidden intrinsic information corresponding to the stored intrinsic information is recorded on at least one of the card surface and card cross-section by use of an infrared absorbing material which is invisible in a visible light region.
7. The IC card of claim 6 , wherein said hidden intrinsic information is recorded by use of a bar code.
8. The IC card of claim 6 , said hidden intrinsic information comprising at least one of information of an intrinsic card number and information of a personal certification.
9. The IC card of claim 8 , further comprising:
an image receiving layer provided on one of said two base plates; and
a writing layer provided on the other base plate;
wherein the information of personal certification including a name and a face image is recorded on the image receiving layer.
