METHOD AND APPARATUS FOR CHANGING ELECTRONIC CARD CARDS {METHOD AND APPARATUS FOR CHANGING CLASS OF ELECTRONIC CARD}

The present invention relates to a portable terminal, and more particularly, to a method and apparatus for changing a card type of an electronic card in a portable terminal having a built-in electronic card capable of charging money.

The use of cards has become commonplace based on the development of the information industry.

At present, a payment service is provided that pays with the amount of money that is charged in the card rather than cash as a payment method.

For example, payment services can be used to pay for transportation charges for public transportation such as subways or buses.

However, in the case of buses, the transportation fare system is divided into the general public, secondary school students, college students, elementary school students, etc., and in the case of the subway, the transportation fare system is usually divided into the general public and students.

Therefore, when the card is employed in the service for paying the transportation fee, the card must be sold according to the purchaser's identity.

For example, the color of the card can be used to distinguish the card type according to the purchaser's status.

However, if the initial purchaser was a student, the status may change after a certain period of time.

For example, graduated from high school or college can be changed to the public.

In this case, the type of card must be changed. However, even if the purchaser continues to use the card without changing the type of card even if the identity is changed, there is a problem that the transportation company must bear economic loss.

In addition, conventionally, there is a problem that wastes unnecessary money when issuing a new card to the purchaser whose identity has been changed and discarding the old card returned.

Accordingly, the present invention provides a method and apparatus for changing the card type of an electronic card, which is designed to change the type of a card by a wireless signal by integrally combining an electronic card capable of charging money in a portable terminal in order to improve the conventional problem. The purpose is to provide.

The amount charge calculation unit 160 transmits and receives the amount of charge or use information with the card charger or card reader, and displays the details on the display unit 120 when the request for confirmation of the details is received from the wireless signal processor 140. Reads the charge amount, card type data stored in the) and transmits the data to the wireless signal processor 140.

The information processor 180 may be configured as separate hardware or may be programmatically embedded.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

For the present invention, a wireless communication service provider should provide a subscriber with a deposit and withdrawal service in connection with a financial institution.

That is, in order to implement the present invention, a wireless communication service provider should establish a communication network with an exchange bureau, a financial institution, an affiliated store, a card company, and a value-added communication network (VAN) service provider. A communication network between the two must be established.

First, an operation of charging a desired amount of money in an electronic card using a communication network will be described.

A PC or telephone can be used to wirelessly charge an electronic card coupled to a wireless pager. For example, if using a telephone, the subscriber calls his pager number on the telephone.

In this case, the wireless communication service provider system determines whether the number is available and if the number is available, 'call phone number', 'voice memo', It provides the calling subscriber with an auto-answer voice message to request the selection of 'charge money', 'suspension', 'unsuspend', 'renew personal information', and the like.

Therefore, if the subscriber wants to charge the electronic card, and the subscriber presses the numeric key or the symbol key corresponding to the 'charge', the wireless carrier system determines that the charge is 'charge' and inputs how much to charge. When the auto answering function is executed and the subscriber presses the numeric key corresponding to the desired amount, the subscriber detects this and sends a voice message to the subscriber to select whether or not to terminate.

Here, in the case of 'charging money', the user may require the input of a password at the beginning of the operation, or after the numeric key for the desired charging amount is pressed, the password is input.

Accordingly, when the subscriber selects the 'charge amount' mode and inputs a desired amount, the wireless carrier system opens a communication through a value-added network (VAN) or directly with a financial institution linked to the desired amount in the account of the subscriber. If there is an amount that can be charged and there is enough to charge it, the subscriber's pager will be called.

In addition, when the subscriber's wireless pager receives a signal transmitted from the wireless service provider, the wireless signal processor 140 searches for the presence or absence of a signal of a predetermined pattern to determine whether it is a general call or information related to charging the money.

At this time, when the amount of money charging operation, the wireless signal processing unit 140 detects a signal of a predetermined pattern, and determines that it is information related to the amount of money charging rather than a general call, and transmits the received information to the information pattern processing unit 150.

Accordingly, the information pattern processor 150 searches for the transmission signal from the wireless signal processor 140 and determines whether it is money charging information or card type change information, and transmits it to the money charging operation unit 160 or changes the card type. It is determined whether to transmit to block 170, and whether there is a checksum error.

If the checksum error is determined, the information pattern processor 150 transmits a command to the radio signal processor 140 to generate an error sound to the tone signal generator 130 while displaying the checksum error message on the display 120. do.

On the contrary, if there is no checksum error, the information pattern processing unit 150 transmits a transmission signal from the wireless signal processing unit 140 to the money charging operation unit 160 by detecting the money charging pattern because the money charging pattern is in operation.

Accordingly, the amount charging operation unit 160 determines whether the information is legitimate information by performing an authentication process on the transmission signal from the information pattern processing unit 150. You will save the amount data you want to do.

Accordingly, the subscriber can pay the price using the electronic card integrated in the portable terminal.

On the other hand, when it is necessary to change the card type by changing the identity of the subscriber, the present invention receives the card type change information transmitted wirelessly to change the type of the electronic card. If described with reference to:

First, if the card type needs to be changed for each subscriber, the wireless service provider transmits the card type change pattern, the specific variable, the traffic card type currently set, the traffic card type to be changed, the transmission date, the encryption value, and the checksum information together to the subscriber terminal. .

In this case, the subscriber station detects a signal of a predetermined pattern in the signal transmitted from the wireless carrier by the wireless signal processing unit 140. The wireless terminal has transmitted the traffic card type change information. Transfer to the processing unit 150.

Accordingly, the information pattern processor 150 determines the card type change information and then determines whether there is a checksum error.

If a checksum error occurs, the information pattern processor 150 transmits the information pattern processor 150 to the radio signal processor 140 to generate an error sound to the tone signal generator 130 while displaying it on the display unit 120.

On the contrary, if there is no checksum error, the information pattern processing unit 150 transmits the transmission signal from the wireless signal processing unit 140 to the card type changing block 170 by detecting the traffic card type changing pattern since the card type changing operation is performed. do.

Therefore, the card type change block 170 performs an authentication process on the transmission signal from the transmission pattern processor 150 to change the card type stored in the memory 190 when it is determined to be a legitimate signal. Referring to the block diagram as follows.

First, when the transmission signal from the information pattern processor 150 is received, the card type change block 170 extracts a specific variable, and the variable comparator 172 is stored in the memory 190. The value of the specific variable extracted by the variable extracting unit 171 is compared by reading the previous specific variable value.

In this case, when the variable comparing unit 172 determines that the specific variable extracted by the variable extracting unit 171 is less than or equal to the previous specific variable value, the change processing unit 177 may change the wireless signal processing unit through the information pattern processing unit 150. 140), it is a variable error and the error code is stored in the memory 190.

Accordingly, the wireless signal processor 140 displays the variable error message on the display unit 120.

On the contrary, if it is determined that the specific variable extracted by the variable extracting unit 171 is larger than the previous specific variable value, the variable comparing unit 172 notifies the change processing unit 177.

At this time, the change processing unit 177 instructs the variable extraction unit 171 to transmit the transmitted information to the card type extraction unit 173.

Accordingly, when the card type extracting unit 173 extracts the card type information currently being set from the information transmitted from the variable extracting unit 171, the type comparing unit 174 compares the card type information stored in the memory 190 with the card type extracting unit 173. FIG. Compare and determine if they match.

If the type comparison unit 174 determines that the card types do not match, the change processing unit 177 notifies the wireless signal processing unit 140 through the information pattern processing unit 150 so as to display the card type on the display unit 120. The authentication error code is stored in the memory 190.

On the contrary, if the card types match, the type comparison unit 174 notifies the change processing unit 177 to the card type extraction unit 173 to transmit the information to the encryption value extraction unit 175. Command

Accordingly, the cipher value extraction unit 175 receiving the information related to the change of the card type extracts a portion or all of the encryption value and stores it temporarily, and transmits the remaining value to the information processing unit 180.

In this case, the information processing unit 180 generates an encryption value using a specific key value previously stored in the memory 190 using the information transmitted from the encryption value extracting unit 175 and compares the encryption value with the encryption value comparing unit 176. To transmit.

Accordingly, the encryption value comparison unit 176 compares some or all of the encryption values temporarily stored in the encryption value extraction unit 175 with some or all of the encryption values generated by the information processing unit 180 to determine whether they match. .

If the comparison result does not match, the encryption value comparison unit 176 transmits an error code to the change processing unit 177 indicating that the encryption value does not match and thus cannot be authenticated.

Accordingly, the change processing unit 177 notifies the radio signal processing unit 140 that the authentication error is an information error and stores the authentication error code in the memory 190.

Therefore, the wireless signal processing unit 140 displays the authentication error message on the display unit 120.

On the contrary, if the password values match, the password value comparison unit 176 notifies the change processing unit 177 of the successful authentication.

At this time, the change processing unit 177 reads the card type information to be changed, the transmission date, and the like among the data used as the encryption input value in the information processing unit 180 and updates the card type information stored in the memory 190 with the card type information currently to be changed. And the information such as the transmission date is stored in the memory 190.

Then, the change processing unit 177 transmits a message indicating that the card type change is successful to the wireless signal processing unit 140 through the information pattern processing unit 150 to display it on the display unit 120.

Here, the card type may be displayed on the display unit 120 by using a specific picture or character to distinguish the card type, and the user may determine the type of the card by looking at the specific picture or character displayed on the display unit 120. .

Therefore, when the card type of the terminal is changed by the above operation, the amount charge calculation unit 160 calculates a payment amount by referring to the card type stored in the memory 190 during the next amount payment operation.

In the above, whether the card type is changed or not is randomly performed by the wireless service provider to determine the identity of each purchaser or, in the case of the transportation card, is changed under the approval of the traffic agent.

The reason for storing information such as an error code or a success code and a transmission date when changing the card type in the memory 190 is that the subscriber reads the information stored in the memory 190 when calling a complaint. To judge and take action.

In addition, the present invention encrypts or decrypts information transmitted from a wireless carrier when a card type change process is performed, and an algorithm called 'Triple DES' may be applied.

The `` Triple DES '' algorithm is used to encrypt or decrypt the DES algorithm three times. The DES algorithm is used to encrypt or decrypt data using a specific key value.

If the wireless communication service provider encrypts the card type for the card type change, the subscriber station encrypts the information processing unit 180 using a specific key value provided by a certification authority such as a wireless service provider and changes the result of the card type change block 170. It can be configured to provide.

Although the above-described case of charging and using an amount like a traffic card, when applied to a credit card, the period of use of the card can be extended by a wireless signal.

As described in detail above, the present invention can change the card type automatically using the card type change information transmitted wirelessly when the card type is changed, thereby providing the user with convenience according to the card change and of course providing economic benefits to the operator. It has an effect.
