Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field The present invention relates to an automatic transaction processing device that inputs a personal identification number or the like from a numeric keypad displayed on a display screen having a switch section on the screen.

[bl Prior Art and Its Disadvantages In an automatic transaction processing device such as a bank's automatic teller machine (hereinafter referred to as ATM), the following procedure is required for a user to receive payment L3. First, insert a cash card or a bankbook with a magnetic stripe into its slot, and enter your PIN number. If the entered PIN is correct, the entered amount will be withdrawn from the user's savings account by entering the payment amount next. Therefore, a PIN number is an important means of user identification in place of a seal. However, although this PIN number is normally kept secret, when entering it into the ATM, it must be entered in public using the numeric keypad, and there is a risk that the PIN number may be known to others. Ta. Therefore, the user has the inconvenience of having to use unnecessary nerves when using the ATV.

FC+ Purpose of the Invention In order to solve the above-mentioned problems, it is an object of the present invention to provide an automatic transaction processing device in which the arrangement of the numeric keypad for inputting a personal identification number is randomly changed before a transaction, making it difficult for others to recognize it.

+d+ Structure of the Invention The present invention is characterized by providing means for randomly changing the display position of each key from 0 to 9 displayed on the display screen of the ATM before a transaction.

(EL Embodiment FIG. 2 is a structural diagram of the main part of the display screen of an ATM which is an embodiment of the present invention. A numeric keypad 1a is displayed on the display screen 1 according to the user's operation. There are 10 numeric keys. It is composed of numeric keys KO-, 9, and cancel key KC.An optical sensor is arranged around this display screen 1.This optical sensor consists of a light emitter and a light receiver, and under normal conditions, The optical sensor 21 with the above configuration detects the presence of a blocking object such as a finger on the optical axis when the light receiving section that receives the light rays emitted from the light projecting section does not receive the light rays.
22, 23 are arranged in order from the left so that their light beams perpendicularly cross the display screen 1, and similar optical sensors 31, 32
．． 33 and 34 are arranged in order from the bottom so that their light rays cross the display screen 1 horizontally. Here, the optical axes of the light beams of the optical sensors 21.2' 2, 23, 31, 32, 33.34 are respectively xi, x2, 3. yi, y2. ”/3
Let ゜yi be y, m (m = 1. 2. 3) and yn (
The intersections of n=1, 2, 3.4) are each numeric keypad KO-
9 and the display position of the cancel key KC. In addition, the numeric keypad KO to 9 and the cancel key KC
A sensor having a transparent electrode thereon can also achieve the same effect as the optical sensor.

FIG. 3 is an example of the display screen of the second embodiment. On the numeric keypad 1a, numbers 0 to 9 are displayed in random order except for the cancel key. The message 1b displays to the user that he/she must input the password by operating the numeric keypad 1a. The manually input password is displayed on the display IC in order from the highest digit. In this example, the password has four digits, and 3 has already been entered in the fourth digit.

FIG. 4 is a block diagram of the main parts of the storage device of the above embodiment. A numeric keypad layout program is stored in area M15, and this program randomly changes the numbers 0 to 9 corresponding to 9 on the numeric keypad KO to 9 before the user inputs the password.

The numeric keypad arrangement processed by this program is stored in area MO-M9. Area MIO is a storage area for key data input by the user. Area M1
6 stores a numeric keypad search program. By this numeric keypad search program, the storage area (MO~
M9) and stores the number in the password storage area (area M11 to area M14).

FIG. 1 is a flowchart showing the processing procedure of the above embodiment. In step nl (hereinafter ni will be referred to as car ni), the numeric keypad 1a is randomly arranged and displayed at a predetermined position on the display screen (n2). When a key is operated by the user (n3), it is determined whether the key operation is a cancel key operation or a numeric key operation (n4).
). If it is a cancel key operation, move the process to n8,
Password memory area M
Clear from ll-M14 and return to n3.

If the operation at n3 is a numeric key, the process proceeds to n5 based on the determination at n4. At n5, the input key data is temporarily stored, and at n6, numerical data corresponding to the key data stored at n5 is searched for and sequentially stored in the password storage area. At step n7, it is determined whether a predetermined number of digits of the password have been manually entered. If the password has not been input yet, the process returns to step n3; if it has been input, the password input process is completed and the process moves to the next step.

When a user enters a PIN number into an ATM with a device configured above, even if someone else is watching, the digits entered manually cannot be determined by the position of the numeric keypad or hand movements, so the user can safely and securely enter the PIN number. You can enter the number.

(F1 Effects of the Invention As described above, according to this invention, the arrangement of the numeric keypad is changed randomly before the user enters the PIN number, so even if someone else is watching, the position of the numeric keypad and the movement of the numeric keypad are changed.) etc., it is almost impossible for others to determine what numbers are being entered.Therefore, users can use AT with confidence.
M can be used, and as a result, it can also contribute to improving the reliability of the store.
