Abstract
A tamper-proof computing device used in conducting a point-of-sale transaction. The tamper-proof computing device comprises a touch-screen display. In some embodiments, an ITO layer is deposited on the touch-screen display that has a tamper line embedded in the ITO layer, such that the tamper line is susceptible to breaking upon unauthorized physical manipulation, and the tamper line is in communication with a microcontroller that is configured to detect the tamper, and to render the tamper-proof computing device inoperable. The tamper line can be a single line trace embedded in the ITO layer or a cluster of traces embedded in the ITO layer. A method of manufacturing comprises forming a tamper line in an ITO layer, depositing the ITO layer on the display and coupling the tamper line to a security microcontroller.
