A personal authentication card with vision inspection security and a method of manufacturing the same

Abstract

This invention relates to a personal authentication card for visual security checking and a method of manufacturing the same. The card C comprises an upper and a lower transparent card support layer 12a, 12b, which sandwich an IC chip 14 and an antenna 16. There is a gradating printing layer 18 put on the upper transparent card support layer, which has a photograph image printing portion 18a (for sublimation heat transfer printing of an image 20). The image printing portion 18a is positioned so that it does not interfere with the IC chip 14 and the antenna 16. An ordinary printing layer 22 with a white matt portion 22a located at the photograph image printing portion 18a is provided on the lower transparent card support layer 12b, and a black printing layer 24 is provided integrally on the ordinary printing layer. A woven pattern hologram gradating layer is provided integrally on the ordinary printing layer. Only the photographic image printing output portion of the personal authentication card is transparent. The face image is outputted by sublimation heat transfer printing and is engraved by watermarking from the back side to make the face image cloudy, and a visual checking both from the front and back sides and a right or wrong judgment of image can be carried out.

Description

technical field [0001] The present invention relates to a personal identification card with visual inspection security and a manufacturing method thereof, more particularly, a personal identification card with high visual inspection security and a manufacturing method thereof, wherein only the printout of the head portrait of the personal identification card is output Part is made of transparent material, and the head portrait is output by sublimation thermal printing method, and the image of the same size as the head portrait is etched from the back through openwork, so that the head portrait becomes blurred, and at the same time, it can be printed correctly, simply and at low cost. Visual inspection and right-false judgment of images from front and back. Background technique [0002] Various personal authentication cards have been proposed, each with visual inspection security (for example, Japanese patent publications WO / 31797 / 1995, 215288 / 1998, 03406 / 1999, 120295 / 1999, 3...

AI Technical Summary

Problems solved by technology

[0018] In order to solve these problems, it is not difficult to use an embedded non-contact type IC chip of 500k bits or more, and use a contact type IC chip with a magnetic tape to improve security, but it has a disadvantage of high cost and outputting and printing a personal authentication card The location of the avatar is restricted

[0019] Personal authentication cards with embedded non-contact IC chips also have a disadvantage that the antenna may be easily cut off by external shocks in the frequency range of use

[0020] As mentioned in the previous section, a personal authentication card that is difficult to forge without PVC sheet material has been proposed, but it is difficult to visually inspect and the output cost of printing the cardholder's avatar is high
