COMBI-TYPE TRANSPORTATION IC CARD HAVING MULTI-TRANSPORTATION CARD ROM DATA AND ITS SETTING METHOD}

The present invention relates to a combi-type traffic card equipped with a multi-traffic card ROM data and a setting method thereof, and more particularly, to a multi-traffic card ROM data that can be used for a conventional traffic card system of a plurality of regions or operators. The present invention relates to a mounted combi transit card and a setting method thereof.

In general, in the use of public transportation, in areas such as Seoul, Busan, etc., a non-contact or combi-type IC card as a means of payment for public transportation is installed in public transportation by embedding a local transportation card application or transportation card ROM data. It adopts a method of payment close to the contactless lead / writer of a transportation card terminal. In addition, these non-contact or combination IC cards are also proposed to be embedded in mobile phones.

Post-paid transportation card, for example, is provided according to a contract from a card van (VAN) via a card issuing means, and through a VAN company and a bank at an exchange By loading the data it can be used as a transportation card. In other words, when using the transportation system, the data of the post-paid transportation card is provided through the card reader / writer of the transportation system (receives the transportation fee) and the local system of the transportation system collected is transferred to the main settlement system. In this case, the state settlement system setstles the transportation card usage fee and is paid by the card van, and the card van is paid by the user.

On the other hand, in the prepaid transportation card, the user can use the means of transportation by charging a predetermined amount through the charging means.

However, in the current transportation card system, there is a problem that a transportation card (prepaid / postpaid) issued in a specific region or a provider system cannot be used in a transportation card system of another region or a carrier.

The current traffic card has a unique authentication system for each card issuer, and the traffic card is authenticated through a secure access module (SAM) or secure interface module (SIM). Each issuer authorizes the use of a transportation card through its own SAM.

Therefore, in order to authenticate various types of transportation cards and collect payment charges for use, it is necessary to install as many SAMs and antennas as the number of issuers of the transportation cards. That is, in order to be able to use various types of transportation cards in one currently used transportation card terminal, an antenna for activating the transportation card, transmitting and receiving radio waves for transmitting and receiving data with the IC chip in the transportation card, and RF modulation RF demodulation module for demodulating the demodulated data and modulating the data on the card terminal side with RF, and if the demodulated data is authenticated, accessing the corresponding traffic card to approve the use of the card and collect the card usage fee. A series of transportation card access systems should be installed for each type of transportation card for each issuer.

In order to solve this problem, the wireless information recording medium multi-access system disclosed in Korean Patent No. 270615 has a plurality of wireless security modules (FIG) for storing information on a common memory area of a traffic card in which a memory area is divided into a common access area and a unique access area. SAM, and receive data and command information for accessing the unique memory area from one wireless security module to process the traffic card function between the unique memory area and one wireless security module. The wireless security module is adopted, and unlike the basic structure of the current traffic card, it is assumed that the memory area of the traffic card is divided into a common access area and a unique access area. It is not suitable for the current general transportation card and terminal system that you do not have. Not only is this impossible, but in order to approve the use of all transportation cards, the common memory area and the unique memory area of the card must be accessed separately, which requires twice as much processing time as the conventional traffic card processing time. This results in an increase in system load.

In addition, RF Patent Application Publication No. 2002-0016752 (published date: March 06, 2002, application number 10-2001-0027944, application date: May 22, 2001) to solve the above problems The multiple access system and multiple access method for a card can selectively authenticate their use at a single card terminal for multiple RF cards issued by multiple card issuers and collect payments for use of the RF card. The present invention provides a multiple access system and multiple access method for RF cards, and provides access to RF card serial and wireless card terminals for RF chip serial number transmission input from the RF card side activated by the radio wave signal of the card terminal. Determining, accessing the RF card memory area by accessing the kit value of the SAM1 through the UART when the access of the RF card is recognized, and accessing the RF card by the kit value of the SAM1. Accesses the card number information or the balance information stored in the memory area, and executes the charge collection routine for the RF card payment payment according to the card payment method, and the memory area of the RF card is not accessed with the kit value of SAM1. SAM2, SAM3,… via UART. , Sequentially calling kit values of SAMn and attempting to sequentially access the memory area of the RF card, and sequentially selecting SAM2, SAM3,... When the memory area of the RF card is accessed by any of the kit values of SAMn, the card number information or balance information stored in the memory area is read, and the billing routine for the RF card payment is performed according to the card payment method. If the memory area of the RF card is not accessed by the kit value of the SAM, determining that the RF card cannot be used.

However, the multiple access method of such a configuration is not only impossible with the current traffic card terminal, but also does not have a large number of cards, and still has a problem that the service is not received in other regions.

In order to solve this problem, we are considering a method of integrating or standardizing and re-installing the SAM installed in the traffic card system terminal. However, standardization is to use a single standardized SAM in all systems. Since it is a built-in method, standardization and integration are not only expensive, but also have a problem of exposing and modifying the SAM of an existing system.

Accordingly, an object of the present invention is to provide a combination type traffic card equipped with a multi-traffic card and a method of using the same. have.

In addition, the present invention provides a method of setting a combination type traffic card having a combination card system for processing a transportation card service by being connected by an RF signal in a transportation card terminal having a unique SAM: Selecting a region in the system; The external system driving the pass applet in the combination card system and delivering the selected area information; And finding a memory start point designated for each region corresponding to the transferred region information, and storing the corresponding transportation card ROM data in the RF EEPROM area as it is. Provide a setting method.

The traffic card ROM data is stored in the initial process of the combination card system, and is configured to be mounted on the RF EEPROM area by inputting local information selected through a contact through menu operation through a man-machine interface (MMI) of a mobile phone system. desirable.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a combination card system 70 of a combination type traffic card equipped with a multi-traffic card ROM data according to an embodiment of the present invention, and FIG. 2 illustrates a mobile phone system 60 and a combination card system 70. The block diagram of the mobile phone built-in multi-transport card system 50 is shown.

In the multi-transport card system embedded in a mobile phone according to the present invention, a combination smart card is installed inside a mobile phone or the like and connected to a mobile phone through a contact interface. As shown in FIG. 1, the combination card system 70 includes a microprocessor 75, a contact portion 77a, a contact interface portion 77, a contactless interface portion 78, an RF antenna 78a, and a ROM ( 76) and EEPROM 74.

The plurality of transportation card ROM data 72 is stored in an area different from the RF EEPROM area 73 of the EEPROM 74, and one selected transportation card ROM data 72 is also stored in the EEPROM 74. The pass applet 71 is stored in the RF EEPROM region 73. To this end, a step selected from the plurality of transportation card ROM data 72 is performed through a man-machine interface (MMI) such as a mobile phone. That is, the EEPROM 74 of the combination card system 70 allows a plurality of traffic card ROM data 72 to enable a traffic card business with a plurality of traffic card terminals 80, and a plurality of traffic card ROM data ( 72 is mounted to the RF EEPROM region 73, which is accessed and read by the driving of the RF antenna 78a, and the traffic card ROM data 72 of each region to enable access to the regional traffic card ROM data 72. It includes a pass applet 71 for fixing the storage location and driving when receiving information of a desired region from the contact portion 77a to mount the traffic card ROM data 72 of the region in the RF EEPROM region 73. It is configured by. In addition, the ROM 76 stores an IC card OS such as Mifare and / or JCOP for booting the combination card system 70.

In the present invention, a pass applet 71 for storing traffic card ROM data 72 for each region is stored in the EEPROM 74 of the combination card, and receiving desired region information from the contact unit 77a and setting it as a transportation card for the region. ) Is mounted. The overall system configuration is multi-transportation in the mobile phone built-in multi-transport card system and the restriction method (mobile-based multi-transport card model) filed by the applicant on July 12, 2002 application No. 10-2002-40580 It has a structure similar to the card model, but differs specifically as follows.

The difference between the multi-transport card model based on the mobile phone and the present invention is that the storage location of the transit card ROM data 72 is different. In the case of a mobile phone-based model, in the process of producing a mobile phone, the traffic card ROM data 72 of the initialization state received from a traffic card company for each region is mounted in the memory of the mobile phone. However, in the case of the present invention, the transportation card ROM data 72 is stored in an area other than the RF EEPROM area 73 of the EEPROM 74 in the card during the initialization of the combination card system 70. In addition, the storage location of the traffic card information for each region is fixed so that the pass applet 71 can easily access the region-specific information.

According to the positional difference of the traffic card ROM data 72, there is a difference in the operation method of the pass applet 71 in the combination card system 70 as described later.

In the present invention, a combination smart card embedded in a mobile phone may be a plug-in type like a subscriber identity module (SIM) of a conventional GSM type and may be configured to be mounted / removed at a predetermined position in the mobile phone. In addition, the antenna for the non-contact interface of the combination card, it is preferable that the box layer member is provided inside the mobile phone as the applicant has already filed separately, both terminals of the antenna for the combination card for the combination card Is connected to a predetermined terminal of the cellular phone board which is plugged in.

In FIG. 2, the mobile phone system 60 is provided with a device driver for the attached combi card, and data is transmitted through the contact portion 77a of the combi card system 70 using the device driver. The mobile phone system 60 is used at the time of input for setting the area.

In addition, the traffic card business is processed by a traffic card terminal 80 including a card lead / writer and a SAM as in the prior art, and thereafter, a fee is charged through a conventional prepaid / postpaid fee collection and settlement system. It is settled and settled. In addition, payment may be made together with the payment of the telephone fee through the mobile communication company, and charged in the mobile phone system 60 regardless of the upfront payment from the mobile communication company as in the transportation card charging system, and in the mobile phone system 60. By transmitting the charging data through the contact portion 77a of the combination card system 70, it can be used like a conventional rechargeable transportation card.

The traffic card ROM data 72 is stored in the initialization process of the combi card system 70, and the local information selected by the menu operation through the man-machine interface (MMI) of the mobile phone system 60 is contacted through the contact unit 77a. By input, it is mounted in the RF EEPROM area 73.

In the process of mounting the multi-transport card ROM data in the combination type traffic card in Figure 3, the step of asking whether the storage card ROM data 72, and if there is data to be stored, if there is a storage space again, the storage, It is possible to store the space when there is a space, and after the storing, by creating a storage location table for each area information, the traffic card ROM data 72 can be read quickly and easily at the time of selection. If there is no transit card ROM data 72 to be stored, the operation is terminated.

After the traffic card ROM data 72 is stored in the EEPROM 74 in the initialization step, as shown in FIG. 4, the user is setting / verifying the traffic card by menu operation using the MMI of the mobile phone system 60. When the setting is selected, the region or type is selected and, accordingly, the region information or the type information is transmitted through the contact portion 77a and the contact interface portion 77 of the combination card system 70. The path applet 71 is driven by the microprocessor 75 to read the traffic card ROM data 72 corresponding to the local information and store it in the RF EEPROM area 73 of the EEPROM 74. This process is completed and displayed so as to know the necessary contents of the traffic card ROM data mounted in the RF EEPROM area 73 and ends. In addition, when confirmation is selected in the traffic card setting / confirmation selection step above, necessary contents are read from the traffic card ROM data stored in the current RF EEPROM area 73 and displayed on the display of the mobile phone system 60.

In this way, when the user wants to use the transportation means by the transportation card ROM data stored in the RF EEPROM area 73, authentication can be performed by the SAM of the transportation card terminal 80, thereby completing the transaction.

Although the above has been described as being limited to setting the RF EEPROM area 73 as one of the transportation card ROM data 72 using the mobile phone system 60, it may be applied to a PDA or the like.

However, when the traffic card embedded in the mobile phone system 60 is used, the traffic card ROM data requested by the user may be transmitted through wireless data communication and stored in the plurality of traffic card ROM data 72. In addition, whenever the use of the traffic card in the combi card system 70 occurs, the usage history may be transmitted to the mobile phone, and the mobile phone system 60 may display the recent usage history and the cumulative usage by storing it in the usage history memory unit. Will be. In addition, in the case of a black list, the restriction code is transmitted via the mobile telecommunication company, and the traffic card ROM data 72 or the RF EEPROM area of the combi card system 70 is transmitted through the mobile phone system 60. It may be possible to restrict the use of the transit card ROM data stored in 73). Such setting may be made by a user's application, a request from a mobile communication company or a transportation card system or a public transportation operator.

As described above, in the present invention, the traffic card ROM data 72 for each region is stored in the EEPROM 74 of the combination card, and also receives the desired region information from the contact interface unit 77 and sets it as the transportation card of the region. Although the pass applet 71 for working is mounted and configured, the mobile phone-based model mounts the traffic card ROM data of the initialization state received from the traffic card company for each region in the process of producing a mobile phone, but in the present invention The card ROM data 72 stores the traffic card ROM data 72 of each region in the EEPROM 74 in the process of initializing the combination card system 70. ) Is stored so that the path applet 71 is easily accessible so that the path applet 71 is driven from the mobile phone system 60, and the selected area information is transmitted. Then, by quickly finding the memory starting point designated by the region by the pass applet 71 and storing the contents of the memory in the RF EEPROM region 73, the traffic card setting is completed. At this time, the mobile phone can transfer the area code to the card and perform other tasks.

However, in the case of a mobile phone-based model, when the user selects a region, the mobile phone drives the pass applet 71 mounted on the combination card and transmits the corresponding region card information stored in the mobile phone ROM through the contact interface unit 77. The path applet 71 executed in the JCOP (OS) receives the continuous traffic card information and the location information transmitted according to the ISO7816 protocol through the contact interface unit 77 in the phone, and the specific location of the EEPROM 74 in the card. The card setting is completed by saving the card to the mobile phone. Until then, the mobile phone only performs the card setting work without doing anything else. Therefore, the present invention has the advantage that the processing speed is faster than the mobile phone-based model.

In other words, the more information is exchanged between the mobile phone and the card, the slower the processing speed will be. In the case of a mobile phone-based model, it takes some time to set up a traffic card because the entire traffic card information is transmitted from the mobile phone. However, in the case of the present invention, since the information transferred from the mobile phone to the card is about a region code and the movement operation between the memories in the card is performed, the setting time is shorter than that of the mobile phone-based model.

However, there is a limit in storing a plurality of traffic card information in the limited memory of the combination card. If the traffic card information is 1K and the EEPROM 74 of the combination card is 8K, considering only the storage area of the pass applet 71 and the area occupied by the RF EEPROM area 73, only about 6 pieces of traffic card information are available. Can be stored. If EMV or other information is stored, the number will be even smaller. Mobile phone-based models can use more than 64K of memory provided by mobile phones, so it can hold more local information, and the card is equipped with only Pass Applet 71, so it can be loaded with EMV or other Applets and information to provide various functions. There is an advantage.

While being used and described as a multi-transport card as a transit card above, the present invention can be used for various purposes without being limited to this purpose. That is, one card can be used as a transportation card, credit card, membership card, etc., and by setting in advance, transactions including authentication, etc. can be made quickly and accurately.

According to the configuration and operation of a combination type traffic card equipped with a multi-traffic card ROM data and a setting method thereof according to an embodiment of the present invention described above, a plurality of traffics different from each system are maintained while maintaining the SAM of the traffic card system. The card ROM data 72 is stored in the EEPROM 74 of the combi card system 70, and the RF EEPROM area 73 is set by the local information from the contact interface unit 77, thereby revealing a conventional SAM or The complicated process of changing is unnecessary, and the issuance of the transportation card ROM data 72 can be used for all transportation card systems, as well as minimizing the costs and inconveniences of carrying and issuing several cards. The user can immediately check the usage history with a simple operation or restrict the use of a blacklisted transportation card simply and quickly. There is an effect such that you can.
