Foldable card case with electromagnetic wave shielding function

Abstract

This product provides a card case that prevents unintentional information from being read from cards that can read information wirelessly using electromagnetic waves. [Solution] This invention provides a foldable card case comprising a first storage section 3, a second storage section 4, and an electromagnetic wave shielding member 2. When the first storage section is folded in half, it is covered by the electromagnetic wave shielding member, which suppresses contactless reading of the stored card. When the card case is opened, contactless reading of the card stored in the first storage section becomes possible.

Description

Technical Field

[0004] , , , , ,

[0001] The present invention relates to a card case for storing a card equipped with an IC chip, and more particularly to a card case capable of switching the availability of non-contact communication according to the storage state.

Background Art

[0002] In recent years, cards having a non-contact communication function such as a My Number card, a credit card, an employee ID card, a transportation IC card, etc. have been widely used. While these cards are highly convenient, there is a possibility that information acquisition by unauthorized reading devices or unintended communication may occur. Therefore, a card case having an electromagnetic wave shielding function is known. However, a conventional card case with an electromagnetic wave shielding function has a problem that when using the stored card, it is necessary to take it out of the case, resulting in a decrease in convenience in ticket gates of transportation facilities or access control systems for rooms.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The present invention · protects important cards from unauthorized reading · allows necessary cards to be used while stored and aims to provide a card case.

Means for Solving the Problems

[0004] The card case of the present invention has a foldable structure. Such a foldable structure may be only a two-fold structure, or in addition to the two-fold structure part, there may be a structure in which there is a further folding part other than the two-fold part, a structure in which the electromagnetic wave shielding member described later slides to open the shielding state, etc. An electromagnetic wave shielding member is disposed in the storage portion inside the card case. When the card case is closed, that is, folded and closed by its folding structure, the cards stored in the internal compartment are covered by an electromagnetic shielding material, suppressing contactless communication from the outside. On the other hand, when the card case is opened, that is, when the folding structure is released and the case is opened, the shielding state is removed, and cards can be read while they are still stored inside. Furthermore, the outer storage compartment on the back of the card case does not have an electromagnetic wave shielding material, allowing the use of transportation IC cards and the like while they are stored inside. [Effects of the Invention]

[0005] According to this invention, (1) When closed, it prevents unauthorized reading of important cards. (2) When open, the card can be read without removing it. (3) The external storage compartment is always readable. (4) Security and convenience can be achieved in a single case. (5) Important cards such as My Number cards and transportation IC cards can be stored separately according to their purpose. [Brief explanation of the drawing]

[0006] [Figure 1] Conceptual diagram of electromagnetic wave shielding structure in a closed state [Figure 2] Perspective view of the card case in the closed position. [Figure 3] Front view of the card case when opened. [Modes for carrying out the invention]

[0007] The card case according to this invention not only has the function of shielding when closed and allowing reading when open, but may also include the following modifications and improvements to its configuration. • Placement of the shielding sheet • Positional relationship with the rear storage compartment • A structure that covers multiple storage compartments with a single shielding sheet. • Specially sized for My Number Cards • Windowed structure • Structure including a sliding electromagnetic shielding section • The folding structure is present in parts other than the bi-fold section, resulting in a structure with three or more folds. The first storage compartment is covered with an external material, but the folding cover can be opened further to allow the interior to be seen from the outside, or to be directly touched. [Examples]

[0008] Figure 1 is a conceptual diagram of the electromagnetic shielding structure in the closed state, viewed from the side. It is also a perspective view of the card case in the closed state. Figure 3 is a front view of the card case in the open state.

[0009] In Figure 1, the foldable card case according to the embodiment of the present invention is made of the card case outer material 1 The part that is located on the outside when folded has a structure that faces outwards. This card case exterior material 1 Various bonding materials are used for electromagnetic wave shielding members. 2 It is attached and, when folded, in the first storage compartment 3 However, it is in a covered state. Also, when the folded state is released and opened as shown in Figure 3, the electromagnetic wave shielding member 2 This is the first storage compartment. 3 It will no longer be covered, and electromagnetic waves will affect the first storage unit 3 It will become possible to read the information of the cards stored in it. Also, the second storage section 4 It is an electromagnetic wave shielding material even when folded. 2 Located on the outside of the part that is covered, even when folded, the electromagnetic wave shielding member 2 Card information can be read immediately using electromagnetic waves from a side that does not involve any intermediaries. The foldable card case according to an embodiment of the present invention is not limited to the structure shown in Figure 1, as long as it has a structure that includes the basic configuration for carrying out the present invention shown in Figure 1, without departing from the spirit of the present invention. It may also include members and decorations for adding or providing various designs and aesthetics, as well as structures and configurations that add functions. The foldable card case according to an embodiment of the present invention may be used as a passport case, a smartphone case, or a foldable wallet as long as it has the above basic configuration.

Industrial Applicability

[0010] By providing a first storage part that can be read by opening a foldable structure in a card that can read information non - contactlessly by electromagnetic waves and a second storage part that can be read immediately, it is possible to prevent unintentional reading of information and improve the convenience of non - contact cards and expand the functions of the card case by preventing electromagnetic wave interference, etc., which contributes to industrial use.
