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.
