KR-102961543-B1 - Smart card with dual-bonded UV pattern layers and method of manufacturing the smart card

Abstract

The present invention relates to a smart card having a double-bonded UV pattern layer and a method for manufacturing the same. The smart card comprises: a double-bonded UV pattern layer including a stacked first pattern layer and a second pattern layer; a smart card body having a preset size and thickness; and a UV adhesive layer configured to bond the double-bonded UV pattern layer and the smart card body together, wherein one of the first and second pattern layers is formed by curing a transparent UV curing liquid, and the other is formed by curing a UV curing liquid having a predetermined color. The double-bonded UV pattern layer comprises: a first pattern layer consisting of a first pattern in which lenses of a preset shape are repeatedly arranged; a second pattern layer formed on the surface of the first pattern of the first pattern layer, consisting of a second pattern in which lenses having a shape opposite to the first pattern are repeatedly arranged; and an upper protective layer disposed on the upper surface of the first pattern layer; wherein the color or pattern of the card is configured to change according to the user's viewing angle.

Description

Smart card with dual-bonded UV pattern layers and method of manufacturing the smart card The present invention relates to a smart card and a method for manufacturing the same. More specifically, the invention relates to a smart card and a method for manufacturing the same in which a double-bonded UV pattern layer, composed of a first pattern layer having a predetermined color and a transparent second pattern layer laminated, is mounted on the front of a card body, thereby allowing card information and patterns displayed on the front of the card body to be viewed only from the front, thereby improving the security of card information, and simultaneously configuring the card's color or pattern to change according to the user's viewing angle. Credit cards are used for purposes such as identity verification, payment, and credit extension. Since most users carry their cards at all times, their shapes and designs are becoming increasingly elaborate to imbue them with artistic value and function as accessories. Furthermore, along with services, discounts, and point rewards, the appearance and design of credit cards serve as important factors in card selection. Accordingly, card manufacturers are striving to satisfy the diverse needs of customers by devising cards that differ significantly not only in appearance and design but also in functionality. As part of these efforts, various attempts are being presented to create a colorful card design by adding three-dimensional patterns to the surface of the credit card to provide a three-dimensional effect. Meanwhile, card information such as the card number, cardholder's name, and expiration date is printed on the front of a credit card. However, since this card information is easily visible to anyone, there is a problem that it can be easily stolen. Accordingly, this patent proposes a method to improve both the design and security of the card.
