Description

Wallet with embedded RF card with signal amplifier function {wallet embedding RF card having signal amplification function}

The present invention relates to a wallet, which is described in more detail by integrating a contactless RF card having a signal amplifier function between the outer skin and the inner skin of the wallet.

Cards commonly used today are divided into prepaid cards, debit cards and postpaid cards according to the payment method, and contact or contactless cards according to the communication method between the card and the card reader. .

In addition, depending on the general functions of the card, it can be classified into general plastic card, bar code card using visual bar code, visual card, visual card, RF (radio frequency) card, smart card, etc. In particular, the RF card is a non-contact operating system and a vending machine for getting on and off in security and public transportation means for reading the identity of the passenger due to the ease of use and the speed of processing. It has an advantage that can be suitably employed in the purchase and payment processing in the back.

Therefore, in recent years, all the transportation cards and pass cards combined with credit cards used in public transportation such as buses and subways adopt such an RF card method, and the demand is increasing explosively. I will say.

Then, the general structure of such an RF card with reference to Figure 1 as follows.

Typically, the RF card 1 includes an upper layer 100 and a lower layer 101 forming an outer surface, and a compression antenna provided between the upper layer and the lower layer so as to communicate wirelessly with a card reader. And an inlay layer 104 including the IC chip 103.

In addition, the RF card (1) is standardized to 3.375 inches long, 2.125 inches wide, 0.03 inches thick according to the international standard of the card, the upper layer 100 of the RF card (1) is usually a card number, the name of the user, Various logs and the like are engraved, and the lower layer 101 may have a form in which magnetic strips and the like are attached to be used as a credit card if necessary.

Hereinafter, the method of using the RF card will be briefly described with reference to FIG. 2. For example, the RF card 1 may be connected to a card reader 3 installed in a ticket gate 2 such as a subway. In order to ensure the security and safety of the use, preferably within 100 mm-close proximity, the loop antenna included in the inlay layer 104 of the RF card 1 by radio waves continuously or periodically transmitted from the card reader 3. 102 generates the induced electromotive force.

At this time, the IC chip 103 is driven by the induced electromotive force generated by the loop antenna 102, and the card reader 3 is retransmitted to the card reader 3 by transmitting the data of the card stored in the chip. Will check the usage history of the card.

However, in the case of a typical card user, a number of cards including such an RF card are carried in his wallet. Frequently, cases are lost from the wallet.

In other words, the wallet itself is not usually lost well, but the RF card in the wallet has been lost a lot, which is not only personally economically damaging but also a large number of RF card reissue There is a waste of cost and resources.

In addition, the conventional RF card has a problem that various problems occur because the reliability in the signal exchange with the card reader is degraded in the state stored in the wallet.

That is, when the distance between the card reader 3 and the RF card 1 installed in the ticket gate 2 of the subway or the like falls within a certain range, the card reader 3 sends out data of the card to the card reader 3 so that the card reader 3 The usage history of the card is checked, but in the conventional state, the signal transmitted from the RF card to the card reader 3 is received even though the distance between the RF card 1 and the card reader 3 is within the reading range. There was a problem in that it was weak and caused a signal to be notified of the readout, and thus was inconvenient to others as well as to themselves due to the hassle and time delay of bringing the wallet back.

In particular, when a crowd is crowded or when a card reading is not done properly at one time during a busy commute, it may cause discomfort and sorry for the back people waiting in line due to time delay. The situation is unusual.

On the other hand, when the RF card is lost, there is a lot of possibility that the person who picked up the card would normally use it illegally without any burden. Therefore, it is urgent to prepare an improvement measure to prevent the loss of the RF card in advance.

The present invention has been made to solve the above-mentioned problems. In the case of handcuffs such as wallets, the RF card is lost from the wallet or the like by integrally embedding a non-contact RF card having an amplifier function between the outer skin and the inner skin. The purpose of the present invention is to solve the problem of eliminating the need to purchase an RF card separately, and to significantly improve the reliability in exchanging signals with a card reader.

According to the present invention for achieving the above object, there is a built-in inlay layer including a loop antenna, an IC chip and a signal amplifier so as to communicate wirelessly with a card reader between the outer skin and the inner skin constituting a known wallet. It is characterized by.

In addition, the inlay layer is formed of a PVC-based material in addition to the above-described configuration, characterized in that the sealing member surrounding the inlay layer is filled in the space between the outer shell and the inner skin of the wallet in which the inlay layer is embedded.

Attached Figure 3 is a perspective view showing a wallet with the present invention contactless RF card, Figure 4 is a partial cross-sectional view shown by cutting the main portion of Figure 3, Figure 5 is a longitudinal cross-sectional view of the AA line of Figure 3, In the configuration of the same components as those of the conventional components, the description thereof will be omitted, but the numerals given in the description of the prior art will be given as it is in the drawings.

In addition, the contactless RF card of the present invention may be composed of only an inlay layer including an amplification unit, it will be revealed in advance that it may be configured to include a sealing member surrounding it in addition to the inlay layer.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 3 to 5 as follows.

According to the present invention, the loop antenna 102, the IC chip 103, and the signal amplifying unit 102 can communicate with the card reader 3 between the outer shell 4a and the inner shell 4b constituting the known wallet 4. An inlay layer 104 comprising 105 is embedded.

At this time, it is preferable that a sealing member such as silicone rubber 5 surrounding the inlay layer 104 is filled in the space between the outer skin and the inner skin of the wallet having the inlay layer 104 embedded therein.

The operation of the present invention configured as described above is as follows.

First, when the wallet with the inlay layer 104 according to the present invention is brought close to the card reader 3 installed in the ticket gate 2 such as the subway, the inlay layer 104 embedded in the wallet 4 is provided. Since the signal amplified by the provided signal amplifying unit is amplified and sent out from the chip, accurate card reading is always possible within the set reading range.

That is, when the wallet 4 with the RF card of the present invention is brought close to the card reader 3, the data is read out of the RF card by the card reader within the set reading range unlike the prior art. The inconvenience of having to put the wallet back due to an error and time delay can be eliminated.

On the other hand, the size of the RF card embedded in the wallet 4, that is, the inlay layer 104 depends on the size of the wallet, but in general the flow by matching the size of the space between the outer shell 4a and the inner shell 4b. It is preferable that the material is formed as a PVC-based material adopted as a conventional card material.

In addition, the outer side of the inlay layer 104 inserted between the outer shell 4a and the inner shell 4b of the wallet 4 is further provided with a sealing member for enclosing the inlay layer 104 of the wallet 4, The inlay layer 104 is spaced apart from the inner surfaces of the outer shell 4a and the inner shell 4b so that the inlay layer 104 made of PVC is damaged by the load and impact applied to the wallet 4 during use. It is possible to prevent the closing.

In this case, in particular, the sealing member is preferably made of a waterproof material to prevent moisture penetration into the inlay layer 104.

That is, for example, when the silicone rubber 5 is applied as the sealing member, the silicone rubber 5 serves as a waterproofing agent to prevent moisture from penetrating into the loop antenna 102 or the IC chip 103 of the inlay layer 104 due to the characteristics of the silicone rubber. Of course, since the shock absorbency and flexibility is added, the shock and deformation applied to the inlay layer 104 embedded in the wallet 4 are well absorbed to serve to protect the inlay layer 5.

Of course, in this case, the silicone rubber 5 should be filled in an appropriate amount within a range in which the volume and thickness are not greatly expanded in consideration of the function and aesthetics of the wallet 4.

Meanwhile, the sealing member may be filled between the wallet envelope and the inner skin where the inlay layer 104 is inserted as described above, but in addition, the sealing member may be manufactured in a sheet form having an adhesive layer to form the inlay layer 104. It may be pre-attached to both sides of the inlay layer 104 prior to being sandwiched between the outer shell 4a and the inner shell 4b of the wallet 4, and a packing or thin tube encapsulating the inlay layer 104. It can also take the form of a tube.

In addition, since the wallet 4 is normally folded in two or more layers when applied to an actual wallet, any of the areas of the outer skin 4a and the inner skin 4b located on both sides of the folded portion, respectively. The inlay layer 104 may be embedded in an area of the, and may be embedded in all sides of the wallet exposed to the outside.

That is, even if a pass card that combines a traffic card and a credit card function is built into both sides of the wallet 4, for example, when passing through the subway ticket gate, only the card on the near side exchanges signals with the card reader 3 There is no worry of imposition.

In addition, the present invention has been described as being limited to only the purse as described above, but the present invention is not limited to this, and both in handcuffs such as a business card holder or a small handbag without departing from the technical idea. It is stated that it is applicable.

The present invention prevents wear and damage caused by the loss of the RF card from the wallet and the exposure of the card to the outside as the contactless RF card is embedded in the wallet, and the wallet and RF card are separately purchased from the buyer's point of view. The hassle had to be eliminated to provide the effect.

In other words, the present invention provides the effect of reducing the social loss due to resources and costs required for reissuance of the card to compensate for the shortage caused by the loss as well as the individual's economic loss due to the loss and reissue of the RF card.

In particular, the present invention is a very useful design that can solve the wasted time and inconvenience caused by the card reading error and the resulting rereading by significantly improving the reliability in the signal exchange between the RF card and the card reader.
