Abstract: The present invention is an information entry system comprising a touch panel monitor screen, wherein the touch panel monitor screen displays keys for information entry, which are arranged circularly in order and the keys are rotationally shifted by a random number of key units around the center of the circular arrangement without changing the order when a user touches a predetermined option key before or after the information entry. This system also has a central processing unit and a program storage unit including an Information entry Screen Generator, a Random Number Generator, a Key Moving Unit, and a PIN Information output unit. This information entry device prevents a PIN or any other information entry from being stolen by someone who glances at the finger movement, since the entire series of the entry keys are rotated before or after the PIN entry.

Abstract: The objective of this invention is to protect the information entry such as a PIN from theft by observation of the finger movement based on the conventional fixed arrangement of entry keys. The present invention is an information entry system comprising a touch panel monitor screen, wherein the touch panel monitor screen displays keys for information entry, which are arranged circularly in order and rotates around the center of the circular arrangement without changing the order when a user touches a predetermined option key.

Abstract: The objective of this invention is to protect the information entry such as a PIN from theft by observation of the finger movement based on the conventional fixed arrangement of entry keys. The present invention is an information entry device including: keys for information entry; a circular support base on which the keys are mounted concentrically and arranged circularly in order, the support base being rotatable around the center of the circular arrangement for enabling a user to rotate the entire series of the mounted keys without changing their order around the center of the circular arrangement before or after the information entry; and an information discriminator for identifying the respective information of selected keys. This information entry device prevents a PIN or any other information entry from being stolen by someone who glances at the finger movement, since the entire series of the entry keys are rotated before or after the PIN entry.

Abstract: The purpose of this invention is to solve the problem to be stolen a glance of PIN or password when we enter it using the information entry device: PIN pad etc. The fixed arrangement of keys makes other person recognize PIN we entered by stealing a glance of the movement of our finger and expecting the number from fixed arrangement of keys in spite of not recognizing directly number of keys we pushed.
