The present invention relates to a public telephone capable of using a contactless wireless recognition card, and more particularly, using a magnetic stripe card (M / S card) and a contact IC card as well as a contactless wireless recognition card (hereinafter referred to as "RF card"). It relates to a public telephone capable of using a contactless wireless recognition card configured to be used up to all.

With the establishment of the information age, various types of cards are diversified, and thus, from simple recording media such as magnetic stripe cards, they are now provided with IC (Integrated Circuit) cards that have been intelligently assigned chips.

At present, the public telephones used in Korea are configured to use only magnetic stripe cards and contact IC cards, and the use of contactless wireless identification cards is impossible at all.

Therefore, in order to use the non-contact wireless identification guard, a separate public telephone for contactless wireless recognition card must be separately installed. There was a problem of spending a lot of budget according to the installation cost.

In addition, if different types of public telephones are installed in one place, public telephone users may be confused, and the telephones may become inoperable counterparts and cause a breakdown when a card that is not suitable for the telephone is used. I could not.

Therefore, the present invention has been devised to solve such a conventional problem, and an object of the present invention is to enable the use of both magnetic strip cards, contact IC cards, and contactless wireless identification cards without distinguishing the types. The present invention provides a public telephone capable of using a contactless wireless identification card that provides a convenience for a user to make a call using any kind of the card.

It includes a main control device for controlling to verify the information through the control unit, and a call function module for controlling the formation of the call path between the telephone and the external public telephone line network under the control of the main control device.

Hereinafter, a public telephone capable of using a contactless wireless recognition card according to the present invention will be described in detail.

1 is a block diagram showing the overall configuration of a public telephone capable of using a contactless wireless recognition card according to the present invention, which can be used without distinguishing a magnetic stripe card, a contact IC card, and a contactless wireless recognition card by type. A security module 200 for preventing unauthorized use of an unverified card such as a tampered or forged card by analyzing the information of the card reader 100 and the card reader 100, and the card. The main control unit 300, which controls all functions of the phone, including the reader 100 and the security module 200, and a call function that enables communication by connecting to an external public telephone line network under the control of the main control unit 300. The module 400 is configured.

Here, the card reader 100, as shown in Figure 2, if the card used in the telephone of the present invention is a contactless wireless recognition guard acts as a medium to exchange information wirelessly with the card in the phone period The loop antenna 110, the RF conversion module 120 for converting data into RF signals to communicate information with a non-contact wireless recognition card through the loop antenna 110, and if the card to be used is a contact IC card IC card contact terminal 130 for transmitting and receiving data through the terminal to be contacted, and the magnetic head 140 to read the information recorded in the magnetic portion of the card if the card used is magnetic strip card. A head encoder 150 for amplifying and converting a minute analog signal of the magnetic head 140 into a digital signal, and an interface buffer for identifying various cards and inputting and outputting the information to the external security module 200 and the main controller 300. It consists of 160.

As described above in detail the procedure according to the public telephone capable of using a contactless wireless recognition card of the present invention.

When the handset is lifted to use a payphone, each element of the circuit including the main controller 300 is initialized with a hook switch input, and the user's card is inserted into the inlet (not shown) of the card reader 100. At the beginning of the insertion, the interface buffer 160 first determines what kind of card is inserted. Here, the interface buffer 150 notifies the main control device 300 of the guard type determination result frame. If the determination content is a contact IC card or a non-contact wireless recognition card, the main control device 300 includes the security module 200. Command to retrieve the password of the card that is inserted into the card reader 100 through. In particular, the interface buffer 160 controls various kinds of information provided by the RF conversion module 120, the IC card contact terminal 130, and the head encoder 150, and the various types of control generated by the security module 200 and the main controller 300. The processing burden of the main controller 300 is reduced by buffering various information provided from the RF conversion module 120, the IC card contact terminal 130, and the head encoder 150 while interfacing the signals. In other words, in the case of the system that does not configure the interface buffer 160, since the main controller 300 should always monitor the signal input from the card reader 100, the processing speed of the main controller 300 is reduced or the call function Cannot be used normally. In order to solve this problem, a main controller 300 having a very high processing speed should be mounted. However, the faster the processing speed of the main control device 300, the higher the price of the main control device 300 significantly, so that the price of the public telephone is increased to reduce the price competitiveness.

On the other hand, in the case of configuring the interface buffer 160 as presented in the present invention, information transmitted from the RF conversion module 120, the IC card contact terminal 130 and the head encoder 150 in the card reader 100 Is temporarily stored in the interface buffer 160, and the interface buffer 160 generates a call signal to the main controller 300 when the amount of information stored exceeds a predetermined amount, so that the main controller 300 can receive the information. Switch. Thereafter, when the main controller 300 is in a state capable of receiving information, the interface buffer 160 transmits the stored amount of information to the main controller 300. Therefore, since the main controller 300 does not need to check whether information is input from the card reader 100, the main controller 300 can normally detect the operation state of the general public telephone. Accordingly, even if the main controller 300 of low performance can be configured, since the normal operating state of the public telephone can be guaranteed, the price competitiveness of the public telephone can be increased.

Here, the security module 200 analyzes the code of the card inserted through the interface buffer 160. If the card is a contactless wireless recognition card, the RF module 200 and the loop antenna 110 are used. The card is searched wirelessly, and if the inserted card is a contact type IC card, the card is searched through the IC card contact terminal 130.

The card search result of the security module 200 is notified to the main control device 300, and if the card is determined to be usable, the main control point 300 is displayed through the display device to zoom and display the call function module ( By controlling 400, it connects the telephone line and makes a call available.

If the card initially inserted into the insertion slot of the card reader 100 is a magnetic stripe card, the information of the magnetic part of the card is read from the magnetic head 140 and the read data is converted from the head encoder 150 to be converted into the interface buffer 160. It is transmitted to the main control unit 300 through the).

here. The magnetic stripe card means a bank credit guard. The availability of the magnetic stripe card should be in accordance with the approval result of the bank network (not shown). Therefore, the information recorded on the magnetic stripe card should be notified to the banking network. .

therefore. The information on the magnetic stripe card inserted in the card reader 100 is transmitted to the bank network through the telephone line via the call function module 400 by the command of the main controller 300, and receives the approval result received from the bank network. Analysis is to determine whether the magnetic stripe card can be used.

Here, if the main controller 300 analyzes the received approval result and determines that the magnetic strip card is usable, the main control unit 300 controls the call function module 400 to connect the telephone line to enable the call.

As described in detail above, according to the present invention, a public telephone can be used without any distinction between the magnetic stripe card, the contact IC card, and the non-contact wireless identification card. Not only does it provide convenience for making a call even when using a kind, but it also saves a lot of budget according to the installation cost because it does not have to install a pay phone for each card type.
