The present invention relates to point of sale terminals generally and more particularly to security systems useful therewith.
The following prior art publication is believed to represent the current state of the art in capacitive security systems:
GB2372363A
The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which:
FIG. 1A is a simplified partially pictorial, partially sectional illustration of a point of sale device constructed and operative in accordance with a preferred embodiment of the present invention;
FIG. 1B is a simplified partially pictorial, partially sectional illustration of a point of sale device constructed and operative in accordance with another preferred embodiment of the present invention;
Reference is now made to FIG. 1A, which is a simplified partially pictorial, partially sectional illustration of a point of sale device constructed and operative in accordance with a preferred embodiment of the present invention, and to FIG. 2A, which is a simplified exploded view illustration of the point of sale device of FIG. 1A. For the purposes of the present description and claims, the phrase “point of sale device” includes, inter alia, a payment terminal, an electronic cash register, a pin pad, an ATM, a kiosk and any other device which stores secured electronic data.
As seen in FIGS. 1A and 2A, a point of sale device, here a PIN pad 100, includes a housing formed of a bottom housing portion 102 and a top housing portion 104. A printed circuit board 106 is located within the housing, as is a keypad assembly including keys 110 which extend through corresponding apertures 112 in top housing portion 104. A display 114 is also mounted on top housing portion 104.
A protected enclosure 116 is located within the housing and includes a top enclosure portion 117 defined by a portion of printed circuit board 106, a bottom enclosure portion 118 and a peripheral enclosure portion 120. The protected enclosure 116 is preferably constructed and operative in accordance with the teachings of applicant/assignee's U.S. Pat. No. 6,853,093, the disclosure of which is hereby incorporated by reference.
