I could see a more effective solution being embedded chassis intrusion meshes.
Disrupt the meshes in any way (EG drilling) would result in three actions.
1) Electronic erase MOST programmable memory in the machine. (Brick it)
2) Engage something akin to an EMO (Emergency Machine Off)
3) If an uplink of some sort exists, broadcast repeatedly on it that such an event occurred and the current uptime.

I wouldn't be surprised if increased physical security on ATMS isn't worth the practical difference in losses.
- mjevans 10y agoSure, someone COULD do that, but how long and how fiddly is that process? How big of a risk is there to disrupting internal components. What if you sandwich the sensitive layer as a thin mesh encased in weak resin between two metal plates? The point of security isn't absolute, but to ruin the risk + effort vs reward balance.
- ams6110 10y agoEasier than fitting a mesh would be an internal vibration sensor/microphone tuned to detect drilling/sawing.
- mjevans 10y agoThat's way easier to trigger a false positive on... Not that my mesh idea doesn't need fine tuning as well. The drilling idea I could see someone just walking by with a very loud powertools song... watch the ATM brick in the face of their first amendment freedom of expression.
