摘要：
A system and method for providing security for a point-of-sale (POS) terminal or an encrypting PIN pad (EPP) by protecting the signals that could be directly probed on a touch sensor electrode grid or remotely probed such as through power supply signals or RF emissions, wherein the drive signals are randomly applied to drive electrodes in order to prevent tracking of drive signals, and charge is injected on sense lines to hide PIN data.
