Description

Apparatus for use limit of RF IC in portable telephone with noncontact type RF IC}

The present invention relates to an electronic chip use limiting device of a mobile phone with a contactless electronic chip. More specifically, in a mobile phone having an electronic chip and a loop antenna, a use limiting device for removing a magnetic field generated from a loop antenna is provided. By connecting between an electronic chip and a loop antenna, the present invention relates to an electronic chip use limiting device of a cellular phone in which a non-contact electronic chip is incorporated to limit illegal use of an unregistered electronic chip.

With the establishment of the information age, various types of cards have been diversified, and from simple recording media such as magnetic stripe cards to integrated IC (IC) cards, which are now integrated with chips.

That is, an electronic chip embedded card (hereinafter, referred to as a 'pass card') that can be used in a subway or a bus is classified into a contact card by a contact terminal, a chip, and an RF contactless card. Among them, the contactless card has a loop antenna and a contactless electronic chip (RF IC chip) embedded therein, and communicates with a card reader installed in a bus or subway, so that the fee is settled by a financial server. That is, in this type of transportation card, after the user is first provided with the service, the fare information of the provided service and the unique identifier information of the electronic chip embedded in the corresponding transportation card are immediately or artificially transmitted to the financial server. After a certain period of time (payment date), payment is made by postpay.

In addition, the transportation card using the charging method of the currently used transportation card is a separate charging device by communicating with the card reader to calculate the amount of use from the charged amount information and then re-record the new value information calculated Go to the charging station where is installed, settle a certain amount of money, and use the new amount information after charging this amount.

According to such a conventional RF contactless card, the user is inconvenient because the card must be carried separately, there is a risk of loss of the card, there is a problem in that the inconvenience to go to the charging station to charge the amount of money in the card.

In order to solve this problem, the present applicant has applied for a non-contact electronic chip in the flip of a mobile phone, which is always carried by many users, to achieve the purpose of the card (Patent Application No. 1999-24789 (filed date: November 12, 1999) (Name of the invention: a mobile phone with a contactless electronic chip).

A conventional mobile phone with a built-in contactless electronic chip prevents loss of a traffic card and satisfies the purpose of the card by embedding or attaching a contactless electronic chip embedded in a traffic card on a flip of the mobile phone. There is an advantage that can be conveniently settled using the method.

On the other hand, the authentication method of the currently used traffic card is using a data transmission method. That is, in a state in which the carrier server and the terminal for reading a traffic card are connected to each other, the carrier server transmits black list data to the terminal on a daily basis. Here, the blacklist data refers to 16-byte bad trader data indicating an identification number of an IC chip not registered.

As a result, when the user approaches the transportation card to the terminal while the transportation service provider server and the transportation card reading terminal are connected to communicate with each other, the identification number of the card recorded in the transportation card is transmitted to the terminal. The terminal checks whether the identification number of the corresponding card is included in the blacklist, and if the identification number of the corresponding card is included in the blacklist, the terminal outputs a warning message which is not allowed in the corresponding transportation card, and the identification number of the corresponding card is displayed in the blacklist. If not included, the use of the transportation card is allowed.

On the other hand, in the case of a mobile phone with a contactless electronic chip, the owner of the electronic chip is shipped with the mobile phone without the owner of the electronic chip being determined. It becomes the usable state.

In order to prevent the illegal use of such a transportation card, when a mobile phone with an electronic chip is initially shipped, the carrier server registers the identification number assigned to each electronic chip as blacklist data, and the carrier server. If the blacklist data is transmitted to the terminal connected to the terminal and stored in the terminal, even if the mobile phone retailer sells the electronic chip without registering it, the terminal reads the electronic chip that is not registered as a bad chip, thereby preventing illegal use of the electronic chip. It can prevent. In addition, when the user registers the identification number of the electronic chip when purchasing the mobile phone, the identification number of the electronic chip is deleted from the blacklist data registered in the carrier server, so that the electronic chip can perform the function of a normal transportation card. Can be.

However, according to the conventional electronic chip registration method, the following problem (s) occur.

That is, since the identification number of all the electronic chips of the cellular phone to which the product was initially shipped must be registered as blacklist data in the carrier server and the terminal, it takes a lot of time to manage the blacklist data and the blacklist data in the terminal. The price of the terminal will increase because it must be equipped with a large memory for storing the.

Accordingly, the present invention is to solve such a problem (s), the object of the present invention is to use the electronic device of the contactless electronic chip embedded mobile phone to limit the use of the electronic chip that is not registered using the use restriction device of a simple configuration To provide a chip usage limiting device.

A feature of the present invention for achieving such an object (s) includes an electronic chip and a loop antenna embedded in a predetermined position of the cellular phone, and the radio frequency generated by the card reader as the cellular phone approaches the card reader. In a mobile phone in which a magnetic field is formed at the loop antenna and supplies the driving power of the electronic chip by the magnetic field: to block the magnetic field generated at the loop antenna from being supplied to the electronic chip by the transmission frequency generated from the card reader. A use limiting device connected to a pair of connection terminals for connecting the loop antenna and the electronic chip; The use limiting device is provided so that it can be easily separated from a pair of connection terminals of a loop antenna and an electronic chip without disassembling the mobile phone.

Here, the use limiting device is preferably composed of conductive wires connected to short-circuit between the pair of connection terminals, so as to block the magnetic field generated by the loop antenna from being supplied to the electronic chip.

Hereinafter, exemplary embodiment (s) of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the elements of each drawing, it should be noted that the same elements are denoted by the same reference numerals as much as possible even if they are displayed on different drawings. In addition, in the following description, many specific details such as components of a specific circuit are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It is self-evident to those of ordinary knowledge in Esau. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is an exploded perspective view of an electronic chip embedded mobile phone applied to the present invention, Figure 2 is a detailed structural diagram showing a state in which the electronic chip use restriction device according to the present invention is mounted on the electronic chip in the mobile phone. .

Referring to Figures 1 and 2 will be described the configuration and operation of the present invention.

Various circuits are provided between the rear frame 101 (where the battery is mounted) and the front frame 102 (where the liquid crystal display element and the function button through hole are formed) of the mobile phone 100. A printed circuit board 105 on which the liquid crystal display device 103 and the function button 104 are mounted, and an electromagnetic wave blocking device 106 for removing electromagnetic noise generated by the printed circuit board 105 are incorporated. At this time, the electromagnetic wave shielding device 106 is installed in the form of a thin coating or spray coding in the remaining area except the point where the liquid crystal display device 103 and the function button 104 of the mobile phone 100 is located.

In addition, an RF contactless electronic chip 108 is provided between the front frame 107a (the part facing the function button) and the rear frame 107b (the part where the company logo is attached) of the flip 107 of the mobile phone 100. ) And the loop antenna 109 are integrated in an integrated form. In addition, a support member 110 is installed in the flip 107 to prevent the embedded electronic chip 108 and the loop antenna 109 from being separated.

At this time, the position of the loop antenna 109 is set to face the point where the function button 104 of the mobile telephone 100 is formed. That is, since the liquid crystal display device 103 and the function button 104 of the mobile phone 100 are mounted directly on the printed circuit board 105, the liquid crystal display device 103 and the function button 104 are provided with an electromagnetic wave shielding device ( 106) fail to install Therefore, as shown in FIG. 2, if the loop antenna 109 is installed so as to face the point where the function button 104 is formed among the remaining areas in which the electromagnetic wave shielding device 106 is excluded in the cellular phone 100, As the 13.56 MHz outgoing frequency generated by the reader is received by the loop antenna 109, a magnetic field is formed in the loop antenna 109, and the electromagnetic wave shield 106 is located at a point away from the magnetic field generating region of the loop antenna 109. As a result, the electronic chip 108 is supplied with normal energy. Therefore, I A communication distance of 3 to 4 cm is secured between the ruler chip 108 and the card reader.

Meanwhile, the conductive use limiting device 112 is connected to the connection terminals 111a and 111b to which the loop antenna 109 and the electronic chip 108 are connected. In this case, the use limiting device 112 is connected to the loop antenna 109. It is preferable that the conductors are shorted conductors so that the generated magnetic field is blocked from being supplied to the electronic chip 108.

That is, as mentioned above, when the mobile phone 100 is initially shipped, the use limiting device 112 is attached to the connection terminals 111a and 111b of the loop antenna 109 and the electronic chip 108. On sale, when the user brings the cellular phone 100 close to the card reader, in the loop antenna 109, a magnetic field is formed by the outgoing frequency generated from the card reader, but the generated magnetic field is controlled by the usage limiter 112. Since the electronic chip 108 is not delivered to the electronic chip 108, the electronic chip 108 does not perform the function of a normal traffic card.

However, a seller who sells the mobile phone 100 while the user purchases the mobile phone 100 registers the use of the mobile phone 100 and the electronic chip 108 and simultaneously carries the use restriction device 112. When the telephone 100 is removed from the cellular phone 100 without being disassembled, a magnetic field is formed in the loop antenna 109 by the transmission frequency generated from the card reader, and the magnetic field is normally supplied to the electronic chip 108. The electronic chip 108 secures the driving power. Thus, the electronic chip 108 may perform the function of a normal traffic card.

On the other hand, if the user approaches the card reader without registering the electronic chip 108 for unpleasant purposes, the carrier server determines that the identification number of the electronic chip 108 is an unregistered identification number to obtain the identification number. By adding to the blacklist data and transmitting it to the terminal, the electronic chip 108 can no longer perform the function of the transportation card.

As described above, in the detailed description of the present invention, specific embodiment (s) have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the embodiment (s) described, but should be defined by the utility model registration claims as described below and equivalents to the utility model registration claims.

As a result, according to the electronic chip use limiting device of a mobile phone incorporating a non-contact electronic chip according to the present invention, the following advantage (s) occurs.

That is, the blacklist is restricted by limiting the use state of the electronic chip embedded in all mobile phones shipped in a simple configuration without adding a separate memory for managing the blacklist data of the electronic chip embedded in all mobile phones shipped. Data is easy to manage, and carriers do not have to expand their memory, resulting in economic benefits.
