Tamper-sensing meshes are most effective when they are continuously monitored using a backup power supply when the

Given their niche applications and high cost, devices incorporating tamper sensing meshes tend to be hard to find. For
this survey, we chose 21 different models of card payment terminals, and 6 other devices. All devices were procured from
