Method for starting a keyboard of a self-service terminal

摘要

A method for commencing operation of an encrypted pin pad (EPP) of a self-service terminal. The EPP includes a security module that is capable of encrypting a confidential numeric code entered over the EPP with a PIN key. The EPP has a sensor that detects whether the EPP is installed properly in the self-service terminal or not. The sensor signal is scanned by the security module of the EPP. The EPP automatically goes to a non-operational mode if the sensor signal indicates that the EPP is not properly installed. The EPP, after passing from an operational to a non-operational mode, can only be returned to operation by entering an authorized activation code in the keypad security module.
