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.
