In general, plastic cards can be used instead of cash, such as credit cards, cash cards, and transportation cards, as well as integrated circuit chips that can contain large amounts of information. As a medical card, plastic cards of various purposes are widely used in modern times.

Recently, in order to keep the appearance of the card beautifully, transparent cards using synthetic resin of transparent material such as PVC have been proposed. However, since the above-mentioned transparent card is simply exposed to the inside of the card, it is not possible to meet the needs of modern consumers who are pursuing the variety and uniqueness of the design. Proposed.

Of course, a product advertisement card distributed to consumers for the advertisement of the product has been proposed such as a three-dimensional card using a transparent card and lenticular screen (lenticular screen).

However, the above-described lenticular plate is a series of semi-circular lenses, and although the stereoscopic image can be seen due to the refraction of the light seen by the lens, the manufacturing method is very difficult and the defect rate of product production is very difficult. Very high, special characters such as barcodes or fine letters cannot be recognized by the sensor reading the barcode. Especially, because of the lenticular shape of the lenticular semi-circular convex lens, the hologram sticker required by the card is attached to the front of the lens. Very difficult defeats occur.
