Abstract: A smart safe include one or more note validators. Access to the note validators and internal workings of the smart safe is defined by an applicable level of security at the smart safe. The applicable level of security may be dependent on whether the smart safe is experiencing an error condition and/or the identification of a user trying to access the smart safe. By allowing some users limited access to the note validators, the users may be able to resolve some error conditions without compromising the integrity of notes stored within the smart safe and without relying on dedicated service personnel to resolve the error condition at the smart safe.

Abstract: The invention is a keypad for securely entering personal identification numbers onto automated teller machines (ATM) or similar devices. A frame secures a flexible keypad to a printed circuit board. The front of the circuit includes a set of tamper detection contacts whose electrical circuit is completed by conductive material on the keypad surface. A moat of conductive material surrounds the tamper detection contact. Opening the circuit by removing the keypad or shorting the circuit to the moat initiates a tamper response. Attached to the reverse side of the printed circuit board are security sensitive electrical components. These security sensitive components include a static random access memory storing cryptographic information and a crypto processor. A plastic cover imprinted with a tamper detection grid forming multiple electrical circuits coupled to a tamper detection circuit covers these components. A border of conductive material on the printed circuit board also surrounds these components.
