  • Patent number: 9250709
    Abstract: 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.
    Type: Grant
    Filed: January 8, 2015
    Date of Patent: February 2, 2016
    Assignee: VERIFONE, INC.
    Inventors: Mehran Mirkazemi-Moud, John Barrowman, Christian Eric Schulz, Arnon Aviv, Amihay Avital, Sergey Meron, Dave Faoro

  • Patent number: 8358218
    Abstract: 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 includes an arrangement of electrical contacts arranged on a base surface and a resiliently deformable conductive element, which defines a short circuit between at least some of the arrangement of electrical contacts only when the housing is closed.
