IC Chip Having IR Communication Module

(Technology)

The present invention relates to an IC chip, and more particularly, an IC chip (smart chip) capable of making payment by IR (Infrared Rays) method when installed in a mobile communication terminal such as a cellular phone by providing an infrared communication module integrally. ).

(Background)

Smart cards widely used as credit cards, electronic money, identity cards, etc. can be classified into various types according to their classification criteria. However, IC chips (smart chips) can be classified into contact cards, It can be divided into contactless card and combined card.

A contact card refers to a card in which a card is activated by contacting a card with a contact of an interface device when inserted into an interface device (for example, a contact inquiring device) receiving the contact card. A contactless card is required for an information processing function. The computing element and the memory element are the same as the contact card, but the power supply for driving the IC chip in the card is provided through the coil (RF loop antenna) in the card and uses the electromagnetic induction method for communication with the interface device (RF inquiry device). Speak the type of card you use. Combination card is a form that supports both the contact card and contactless card functions, the most common is Combicard (Combicard).

IC chips (smart chips) applied to smart cards are more difficult to duplicate than magnetic magnetic strips, which are widely used in credit cards, and have excellent security. Therefore, credit cards will be replaced with IC chips instead of magnetic magnetic strips.

The contact smart card is provided with six terminals on the smart chip according to the international standard ISO7816. For example, when the contact smart card is operated on an inquiry machine (contact interface device) for payment, the six terminals are electrically contacted. The data of the smart chip is recorded, updated, and deleted according to the program embedded in the smart chip, which executes functions such as payment and identification.

Smart chip (combi chip) applied to the combination card, by adding two terminals to the smart chip of the contact card according to ISO14443, by connecting the RF loop antenna that can induce induced electromotive force to the added terminal, In addition to the contact application using six basic terminals, when the Combi card is contactlessly approached to the inquiry system, current is induced in the RF loop antenna to drive the Combi chip, which enables the Combi chip to operate the RF inquiry system through the RF loop antenna. By communicating with the (interface device), data stored in the combi chip is recorded, updated and deleted in a non-contact manner.

4 is a schematic diagram of a conventional combination card to which a combination chip is applied. As shown, the combination card 100 is common to the CPU 110, the input / output unit 120, the main storage unit 130 (RAM, ROM, EEPROM), the contactless type to control the entire card in accordance with the control logic 111 It can be seen that the configuration includes a storage unit 140 (EEPROM), an access matrix 150, a wired I / F and logic 160, an RF loop antenna 170, and the like used.

5 is a terminal arrangement diagram of a combination chip according to the ISO standard. As shown, the terminal side of the combi chip has a total of eight terminals C1 to C8, C1 is a power supply terminal, C2 is an initialization input terminal, C3 is a clock terminal, C4 is a spare terminal (antenna terminal), C5 is a ground terminal, C6 is a program voltage terminal, C7 is a serial data input / output terminal, and C8 is a spare terminal (antenna terminal). The RF loop antenna 170 is connected to the preliminary terminals C4 and C8.

Recently, the Combi chip is embedded in a mobile communication terminal such as a cellular phone, not in the form of a plastic card, so that the base terminal of the Combi chip (the above six terminals) and the CPU of the cellular phone are electrically connected to each other. In order to process the data of the Combi chip and the induction electromotive force of the RF loop antenna connected to the preliminary terminals (C4, C8) has been developed to contact the external query and the data.

The inventors of the Utility Model Registration No. 269391 (2002. 03. 03) developed 'IC chip pack for contact / contactless smart card' in which two spare terminals (antenna terminals) were formed on the chip side as well as the terminal side. 11. registration). As a result, the combi chip can be installed in a conventional plastic card such as a credit card as well as in a device such as a mobile phone. The combi chip can be used regardless of the user's location, type of equipment, or service type. It can be used freely by contact and non-contact.

One problem that arises in paying various charges with a mobile phone with a contact / non-contact combi chip incorporating the RF method is that between the RF loop antenna embedded in the mobile phone and the inquiry device due to the action of the electromagnetic wave blocking devices built in the mobile phone. The communication to form the induced electromotive force of the interference is obstructed and the communication distance is inevitably shortened, and thus there is a fear that the communication will be incomplete.

Recently, as a payment method using a mobile phone, a device for including a infrared communication module in a mobile phone and making a payment through infrared data communication with an inquiry device has been proposed (for example, Korean Patent Publication No. 2002-0015084, 2002). 02. 27. Disclosure).

However, the conventional IR payment mobile phone has the advantage that it is possible to transmit and receive data over a long distance up to several meters due to the nature of infrared rays, so that the mobile phone does not need to be approached to the inquiry machine. There is a design limitation to be embedded.

An object of the present invention is to solve the design problems caused by having an infrared communication module in the mobile communication terminal itself in applying the IR payment to the mobile communication terminal, an IC chip widely used in smart cards and the like. Integrating the infrared communication module in the integrated, by mounting the IC chip containing the infrared communication module to the mobile communication terminal is to give the IR payment function to the mobile communication terminal.

Another object of the present invention, in the conventional combi chip that RF loop antenna is connected to the preliminary terminal is used in contact and non-contact, including the infrared communication module to the combi chip while connecting the infrared communication module to the preliminary terminal It is intended to be able to select and use the RF payment method and IR payment method.
