1. A self-service machine, comprising:
- a housing;
a door mounted to the housing for gaining access to the inside of the housing;
a processor; and
a tamper detection mechanism, wherein the tamper detection mechanism includes;
a tamper detection controller;
an emitter; and
a sensor, wherein one of the emitter and sensor is mounted to the housing and one of the emitter and sensor is mounted to the door; and
wherein the tamper detection controller drives the emitter with a signal and monitors the sensor to determine if it generated an inverted version of the signal.

Abstract
This document discusses, among other things, a system, method and kit for detecting tampering within a self-service machine having a housing. An emitter and a sensor are mounted to the housing and to an object positioned in relationship to the housing such that radiation generated by the emitter falls on the sensor when the object is in a particular position with respect to the housing and to a lesser extent otherwise. A signal is generated and the emitter is driven with the signal. The signal is modified and the sensor is monitored for the modified version of the signal. An alarm is generated if the modified version of the signal is not detected.
