{Apparatus for preventing using a card by stealth in an Automatic Teller Machine}

According to the present invention, a binary bit corresponding to a password for theft report is preset for each unique identification data of the card, and a corresponding register value is compared with a password of a card inserted in an ATM, and the card is stolen according to the comparison result. By recognizing and notifying the theft reception system of police or private security companies, it prevents forced withdrawals by robbers who use theft reporting password or illegal users such as thieves, and quickly arrests the illegal users. It relates to a card theft prevention device in an ATM.

In general, cash withdrawal means (credit cards, bank accounts, cash withdrawal cards) are used as a medium for cash withdrawal between financial institutions (card companies, banks) and customers who use these financial institutions. In case of theft or loss of the card, the customer's property penalty is prevented.

Such cash withdrawal means is a service that is normally entered for a specific customer's card on the magnetic tape, and normally withdrawn for a certain period of time from the deposit or financial institution of each customer by a password to solve the input unique identification data Withdrawal is provided.

In particular, in recent years, due to the universalization of credit cards, each individual is issued and used a number of credit cards according to each financial institution, and the cash withdrawal by the credit card is operated by each financial institution. Since the cash dispensers of service companies linked to the institutions are widely distributed and used in any area, criminals seeking cash are easily targeting credit cards for robbery. Since a security system that can be prevented has a single password as mentioned above in each credit card owned by each individual, it is a fact that it is designated as an easy crime target for criminals.

However, each customer's card has only one password entered into the financial institution's computer network, so when the customer is asked for a password while being kidnapped or stolen by a robber or thief, he has no choice but to provide the password. Recently, it has been abused as the easiest cash cutting method for criminals, and has been a problem that can not actively cope with the prevention of customer's personal safety and disadvantages that easily cause a disadvantage of the customer's property.

Accordingly, the present invention has been developed to solve the above-described problem, the binary bit corresponding to the theft report password for each unique identification data of the card is set in advance, and the corresponding resist value of the card inserted into the ATM is output. Forced cash by illegal users such as robbers or thieves who use the password for reporting theft by notifying the theft of the card and notifying the theft reception system of police or private security companies according to the comparison result. It is an object of the present invention to provide a device for preventing theft of a card in an ATM.

Hereinafter, with reference to the accompanying drawings for the present invention will be described.

First, Figure 1 is a view showing an example cash withdrawal theft prevention system to which the present invention is applied.

As shown in the drawing, the system to which the present invention is applied receives a credit card 100 having two passwords embedded therein, and determines whether the password inputted by the hijacker is the same as a preset value in the password storage server. According to the determination result, the cash dispenser 200 outputs the beeping sound signal and the CCTV recording start signal, and starts recording the screen data photographed by the CCTV according to the CCTV recording start data output from the cash dispenser 200. And the CCTV record storage device 300 for transmitting to the theft reception system of the police department or private security company that transmits through a predetermined communication network in real time, and according to the card theft notification-related data transmitted from the cash dispenser 200. Recognizing that the card inserted in the ATM is a stolen card, the result is returned to the police or private office through a predetermined communication network. Displays the bank computer network system 500 that transmits to the theft reception system 400 of the company, and the card theft detection fact and the screen data transmitted to the theft reception system of the police or private security company to patrol police or security company personnel The terminal 600 is configured to.

In the system configured as described above, if a credit card having two passwords is inserted into a cash dispenser of the present invention by a card thief or the like and a password is input, the cash dispenser 200 enters a secret without an input password. It determines whether the same value as the preset value in the number storage server and transmits the card theft notification data and CCTV recording start data to the bank computer network system 500 and the CCTV record storage device 300 according to the determination result.

That is, when the password inputted as a result of the determination and the preset value are the same, the bank computer network system 500 connected the card theft notification data and the CCTV recording start data to a predetermined communication network device by using this as an enable signal. And transmit to the CCTV record storage device 300, and if not the same, and performs an existing card use related system operation such as displaying a password error message on the terminal.

At this time, regardless of the result of the determination, it is preferable that the service routine of the ATM is sequentially operated in a predetermined order without causing any difference from the normal use of the card so that the suspect does not know the card theft report.

Next, the bank computer system 500 recognizes that the card inserted in the ATM according to the card theft notification data transmitted from the ATM 200 is a stolen card and reports the result through a predetermined communication network cable. Or transmit to the theft reception system 400 of the private security company.

In addition, the CCTV record storage device 300 starts recording of screen data photographed by CCTV according to the CCTV record start data transmitted from the cash dispenser 200, and records the recorded screen data in real time with a predetermined communication network cable. Through the transmission to the theft reception system 400 of the police or private security company.

Thus, the fact that the card and the screen data transmitted to the theft reception system 400 of the police or private security company is displayed on the terminal 600, such as a police or security company vehicle patrolling the relevant police or security company This allows you to quickly arrest suspects who are using your password for theft at the ATM.
