Title: PIN PAD
Abstract:
The present invention provides a pin pad provided with: a keypad wiring board equipped with a switch; a control device configured by including a storage unit for storing an encryption program for encrypting an input signal that flows due to the switch being pressed, an output unit for outputting the encrypted input signal to the outside, and an erase unit for erasing the encryption program, the control unit being connected to the switch via a signal wire; and a flexible cable sheet covering the keypad wiring board and the signal wire, and having a damper wire formed at positions facing at least the switch and the signal wire. The erase unit erases the encryption program when a voltage drop in the damper wire is detected.
