JP2005128982A - Holder that enables only one of plurality of noncontact storage media to be operative by electromagnetic wave shielding sheet - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a holder for noncontact storage media, which is capable of preventing radio waves to read cards from reaching the cards other than the target card, to prevent the card from being rejected when a plurality of noncontact storage media (IC cards) are held up to a reader. <P>SOLUTION: An electromagnetic wave shielding sheet 2 is provided between pockets 5 and 6 for storing a plurality of IC cards 3 and 4. The electromagnetic wave shielding sheet 2 is constituted of any one of metal, a metal film, a metallic fiber, a film into which metallic powder is kneaded, and a film on which a metallic film is evaporated. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention relates to preventing a plurality of contactless storage media from competing or interfering on a reader.

When multiple non-contact type storage media (hereinafter referred to as IC cards) are loaded simultaneously, information may not be read correctly due to competition or interference with each other. In addition, there are systems that have the function of rejecting reading when multiple IC cards having the same function are read simultaneously.

There is an invention with a built-in electromagnetic wave shielding sheet on the premise that an IC card is stored like the present invention (see, for example, Patent Document 1). The invention of Patent Document 1 is intended to prevent the information of the IC card from being stolen from the outside by the electromagnetic wave shielding sheet, and between the IC cards stored at the same time like the present invention. It is not intended to prevent competition or interference. This is because the invention of Patent Document 1 has an electromagnetic wave shielding sheet provided outside the storage container, while the invention of this time is installed so as to be sandwiched between a plurality of IC cards. It is clear that these two inventions are completely different in structure and purpose.
JP-A-2003-300579

For example, in a ticket gate system using a non-contact type storage medium that has been put into practical use by JR East, there are three types of cards with the same function, that is, 1) a single function ticket gate system (a fixed amount of money is deposited on the card, 2) A credit card function added to a single function ticket gate system, 3) A commuter pass function added to a single function ticket gate system (usually It is used as a commuter pass, but it is used by subtracting the extra rent from the deposit, etc. All of them function by reading the contents stored in the IC chip with the reader at the ticket gate.

When these cards are put in the same commuter pass or wallet and applied to the ticket gate reader, the message “Multiple cards are used” is displayed and the gate is closed. .

In this case, you may be wondering about the need to put multiple cards in the same wallet, but since Shinkansen commuter passes cost hundreds of thousands of yen, it is essential to carry a card with a credit card function. I understand the necessity of carrying a commuter pass purchased with the credit card at the same time.

In order to read the information on the IC card, the device generates radio waves from the reading device, and the device reads the radio waves returned from the IC card. Therefore, the present inventor prevents the radio wave from acting on the card farther from the reader by sandwiching an electromagnetic wave shielding sheet between the two cards, which is simultaneously held over the reader as in the present invention. , Only one IC card works.

As a result, for example, when using a credit card and commuter pass incorporating a non-contact type storage medium at the same time in an invention commuter pass or wallet, hold the commuter pass side over the reader when commuting. It became possible to prevent competition with credit cards with contact-type storage media, and the gate at the ticket gate was not closed.

An electromagnetic wave shielding sheet (reference numeral 2 in the drawing) is stuck or sewn between a plurality of card pockets (reference numerals 5 and 6 in the drawing) of the commuter pass and wallet so as to be sandwiched between the cards.

In the case of a simple bag-like container that can accommodate a single IC card, an electromagnetic wave shielding sheet may be placed on the external protective film on one side. In this case, it is assumed that this container is used in a wallet or a commuter pass case, and the effect is exhibited only by using the electromagnetic wave shielding sheet side toward the already stored IC card side.

It is appropriate that the electromagnetic wave shielding sheet is composed of any one of metal, metal film, metal fiber, film kneaded with metal powder, and film deposited with metal film.

1 is an external view of a storage container for a non-contact type storage medium according to the first embodiment (wallet) of the present invention. External view of a storage container for a non-contact type storage medium according to the second embodiment (inserting a commuter pass) of the present invention Cross section of FIG. External view of a storage container for a non-contact storage medium in the form of a third embodiment (simple bag-like container) of the present invention Cross-sectional view of FIG. 4 “Mechanical description of FIGS. 1 and 2” For example, in the figure, a commuter pass (IC card A-3-) and a non-contact type each incorporating a non-contact type storage medium in the card pockets 5 and 6, respectively. When a credit card (IC card B-4-) with a storage medium is inserted, when using a commuter pass, hold the A card face down on the reader at the ticket gate, and select "Multiple “The card is being used” is displayed and the gate does not close. If the credit card has been deposited on a contactless storage medium and you get on without using a commuter pass, you can pass through the ticket gate by holding the B card face up. "Mechanical explanation of Fig. 3" When inserting one IC card into this card case and putting it in a wallet etc., the electromagnetic wave shielding sheet side (6) is another piece already in the wallet etc. Insert it into the card. The method of holding it over a reading device such as a wallet is the same as “Mechanical description of FIGS. 1 and 2”.
