POINT OF SALE TERMINAL HAVING ENHANCED SECURITY

摘要

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.

主权项

1. Tamper indication apparatus comprising:
at least one switch assembly including:
an arrangement of electrical contacts arranged on a base surface, said arrangement of electrical contacts including an outer ring contact, at least one intermediate ring contact and a central contact, at least one of said outer ring contact and said at least one intermediate ring contact being an anti-tampering contact; anda resiliently deformable conductive element comprising:
an at least partially continuous circumferential flange fixed in electrical contact with said at least one intermediate ring contact;a circumferential portion including a circumferential arch; anda contact portion disposed, in a first operative orientation, touching said central contact and, in a second operative orientation, at a distance from said central contact; and tamper indication circuitry operative to receive an input from said at least one switch assembly and to provide an output indication of possible tampering.
