Description

ELECTRONIC CASH COUPLED USB CONNECTOR AND RF-CHIP}

The present invention relates to an electronic money for free use of public transportation such as a bus or subway, and more particularly, directly connected to a USB serial port (USB Port: Universal Serial Bus Port) of a computer, without charging the card charging station. The present invention relates to electronic money that combines USBI and RF chips to enable the use of Internet access services and to perform authentication and financial settlement.

The electronic money according to the present invention can be equally applied as a means of payment when all public transportation means including buses or subways are used, and can also be applied to authentication and financial settlement for the use of Internet access services. In the following description, a case where a subway is used as a traffic card will be described.

In the conventional case, in order to use the subway, it has been used in the form of purchasing a ticket in cash from a station attendant at a ticket sales office and then boarding the subway after a ticket gate. However, there was a problem that the station attendant issued the tickets of all subway passengers one by one, that is, the labor cost increased due to the increase in the number of the station attendant and the delay of the subway boarding time of the user.

In order to solve such a problem, in addition to the securities ticket release, a cash dispenser automatic ticket vending machine was developed and installed. However, in the case of directly injecting cash, only a single-use ticket for each section is purchased, which causes a problem to be purchased every time the passenger rides. The problem could not be solved. In particular, even when purchasing a single-use ticket or a flat-ticket ticket, it is impossible to pay with a credit card, which causes inconvenience to users having to carry cash continuously.

Recently, in order to solve the above problems, an electronic money system in the form of RF card (RF-CARD) capable of micropayment has been introduced so that both buses and subways can be used.

However, the amount of the electronic money including the transportation card must be charged at the designated place of the bus stop or at the ticket office in the subway station, and the current balance can only be checked after use, and cannot be paid by credit card. Users have considerable inconvenience.

In addition, RF-CARD is used as a method for authentication and financial settlement for the use of Internet access service, but it is required to use a separate equipment for recognizing RF card. Electronic money, such as post-paid transportation card coming out combined there is a problem that the risk is large.

After all, in order to use the conventional RF card, it is used as a means of payment due to the increase in demand for transportation and micro internet payment, but the method for acknowledging financial settlement relies mostly on software, and the hardware is also simply used as a serial number. As piracy is not sufficiently blocked by the input method, it is difficult to activate at the same time with weak safety.

In addition, when the RF card used as electronic money is damaged or lost, it is difficult to check the balance and receive a refund. In some cases, the balance cannot be confirmed.

The present invention has been made to solve the above problems, the purpose of which is connected to the USB port of the computer USB (USB) and RF chip (RF-CHIP) in electronic money without a separate device By making this possible, it is to provide electronic money combining USB and RF chip that enables users to charge money regardless of the time and place.
