In a card-making method and system, an authentication card is made from a raw
card having a readable and writable information-storing portion formed therein,
by forming the image on the front surface and/or back surface of the raw card and
writing individual authentication information in the information-storing portion.
Processing information of the raw card is written in the information-storing portion.
The image is formed based on the processing information read from the information-storing
portion. Individual authentication information of the authentication card is written
in the information-storing portion after forming the image. In a heat treatment
mechanism for cards, heat treatment is applied to a card having an information-storing
portion arranged in part of a surface of a card body of a card, by using a light
source as a heating source, to thereby fix an image to the card. A light-blocking
plate is arranged such that the light-blocking plate is positioned between the
card and the light source to block irradiated light to the information-storing
portion. An image-forming apparatus incorporating the heat treatment mechanism
is also provided.
