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. The information entry device of the present invention can be adapted for an ATM or POS terminal as well as for a touch panel screen monitor.
