Abstract: There are different solutions on the market for execution of financial transactions, from payments through credit cards and debit cards, to transactions with funds transfers electronic validation. These solutions are possible thanks to the use of dedicated equipment named herein of Safe Equipment. The construction of these facilities is subject to rigorous safe requirements since they deal with funds transactions, falling high degree of responsibility on the providers of such solutions, both for equipment and systems. As the installing processes of a foreign circuit, like “chupa cabra”, necessarily require the violation of the Safe Equipment, is making small openings in the cabinet, or by exchanging parts and components of the equipment, this patent presents a system where the parts used are properly identified in a given Safe Equipment, so that we can conduct an investigation, at any time, of the parts that make up the Safe Equipment under analysis.

Abstract: The invention provides a Control and Monitoring Module internal or external to a Safe Equipment such as: Point of Sale (POS) Terminals, PINPAD Terminals and Encrypted Keyboards, designed and implemented in order to detect current consumption variations of the equipment, thus indicating the presence of undesired circuit inserted in parallel in the original circuit of the Safe Equipment. The Control Module uses electrical current consumption sensors in microprocessor circuits capable of identifying variations in consumption.
