By the above steps, the worker working in the fixed place will provide the service requested by the holder of the identity card (S13).

Next, FIG. 6 shows the system configuration and communication when used in a mobile work place (checkpoint, portable for unchecked checkpoint, various performance halls, etc.). The procedure performed in FIG. However, connection of the information providing server 700 for requesting additional information and receiving inquiry information further requires accessing the wireless network (S16).

In this way, the present invention can be applied to the authenticity and identification of credit cards, various membership cards, documents, etc., and if the user establishes clear principles for accessing information depending on who the user is, the leakage of personal information will be clearly prevented. Could be.

In other words, patrol workers or checkpoint workers will be able to prevent and crack down on crimes using portable card readers pre-populated by criminals, and can easily compare the images displayed on the card with the card readers. This makes it possible to search for forgery and tampering.

At this time, if the size of the perforated image determination device 100 is adjusted according to the size of the object to be checked, the social cost for the socially prevalent concern can be greatly reduced, and various applications will be possible.

As described above, the present invention relates to a perforated image determining apparatus and a method for reading a plate-like medium by means of a perforated image, and more particularly, by restoring a random number perforated image perforated on a plate-like medium by using a perforated image determining device. It is possible to determine whether the plate media are forged, so that the counterfeit desire can be blocked, and at the same time, it is possible to accurately and promptly check whether the plate media is counterfeit. It can be prevented, and the wireless communication technology can be applied to enable effective inspection at a remote location.
