Abstract
Secure touchscreen devices are disclosed. In one embodiment, a secure touchscreen assembly may include a first patterned conductive layer comprising a first touch sensing grid and a first tamper sensing grid, the first tamper sensing grid disposed in areas of the first conductive layer where the first touch sensing grid is not present and is not in physical contact with the first touch sensing grid, and tamper sensing circuitry coupled to the first tamper sensing grid that detects a tamper by detecting change in conductivity in the first tamper sensing grid.
