Amihav Avital

A data entry device including a housing formed of at least two portions, data entry circuitry located within the housing, at least one case-open switch assembly operative to sense when the housing is opened and tamper indication circuitry operative to receive an input from the at least one case-open switch assembly and to provide an output indication of possible tampering with the data entry circuitry located within the housing, the at least one case-open switch assembly including an arrangement of electrical contacts including at least first, second and third contacts and a displaceable conductive element, the tamper indication circuitry and the third contact together being operative such that when the third contact is short circuited to at least one of the first contact, the second contact and another contact, an output indication of possible tampering is provided.

Secure point of sale terminal

A data entry device including a housing including a top housing portion including key apertures, a plurality of data entry keys mounted in the housing to have data entry key depression travel paths in the housing, the plurality of data entry keys being associated with a substrate, which is disposed below the top housing portion and anti-tampering electrical conductors arranged between the top housing portion and the substrate thereby to prevent unauthorized access to the substrate.

Secured keypad devices

A magnetic card reader including a magnetic head, located in a non-secured region, at least one signal path including at least first and second electrical conductors extending from the magnetic head in the non-secured region to a secured region, circuitry located within the secured region and receiving at least one signal output along at least one signal path, the circuitry located within the secured region including functionality ensuring that a voltage difference along the at least first and second electrical conductors is virtually zero, thereby obviating illicit information retrieval via tapping of the at least first and second conductors and analysis of voltage differences therebetween.

Enhanced security magnetic card reader especially useful in point of sale devices

A magnetic card reader including a magnetic head, located in a non-secured region, at least one signal path extending from the magnetic head in the non-secured region to a secured region, signal processing circuitry located within the secured region, an obscuring signal injector located within the secured region and an obscuring signal remover located within the secured region, for receiving a combination of at least one signal output and an obscuring signal and for providing an unobscured signal output, corresponding to the at least one signal output, to the signal processing circuitry.

Security functionality for magnetic card readers and point of sales devices

A magnetic stripe reading device including a magnetic head assembly including a mounting element, at least one information reading sensor having output contacts, the sensor being mounted in the mounting element and a flat cable coupled to the output contacts of the at least one information reading sensor, a portion of the flat cable being arranged in a doubled-over configuration over the output contacts, thereby to provide anti-tampering protection to the output contacts.
