As seen in Fig. I5 the point of sale terminal may be generally similar in structure and function to a conventional point of sale terminal such as a NURIT 810O5 commercially available from Verifone, Inc. It is appreciated that the present invention is not limited in its application to a given type or model of point of sale terminal but is applicable to magnetic stripe reading devices useful in any suitable point of sale device.
Such a point of sale device may include, for example, a check reader, a card-based payment terminal, an electronic cash register, a PIN pad, an automatic teller machine
(ATM)5 an automated kiosk and an electronic vending machine.
As seen in Fig. 1, the point of sale terminal preferably includes a housing 100 including a base portion 102 and a top portion 104, which are typically snap-fitted together. In the illustrated embodiment, the housing also includes a detachable and reattachable printer housing portion 106. The top portion 104 of housing 100 preferably defines a smart-card insertion slot 108, which communicates with a smart-card reader
(not shown) located within the housing. The top portion 104 of the housing 100 also defines a keypad array location 112 wherein an array of keys 113 are located, and a display location 114, where a display, such as an LCD display 116, is located.
Additionally, the top portion 104 of housing 100 preferably defines a magnetic card reader assembly 118, which includes a slot 120 having spaced surfaces 122 and 124. A magnetic head assembly 130 is mounted on surface 122, typically on an inside wall of surface 122.
A printer (not shown) is disposed within printer housing portion 106 and cooperates with a roll of paper (not shown), which is supported on a paper roll holder
(not shown) located within printer housing portion 106. Printed receipts 138 are output via a printer paper slot 140 defined between an edge 142 of top portion 104 and a corresponding edge 144 of a paper roll cover 146.
Reference is now made additionally to Fig. 2, which illustrates a magnetic head assembly 130 constructed and operative in accordance with a preferred embodiment of the present invention, which is useful in the magnetic card reader assembly 118. As seen in Fig. 2, the magnetic head assembly 130 preferably comprises a mounting element 202 which is typically mounted onto surface 122 of top portion 104. Mounting element 202 is preferably formed of metal and preferably defines a peripheral enclosure 210 having an end slot 212 and two bifurcated side slots 214, each defining a ground contact 216. Extending axially sideways from the peripheral enclosure 210 are two winged, generally planar, somewhat flexible mounting portions 218 having mounting apertures 220 formed therein. An information reading sensor 230, preferably a magnetic stripe reading sensor, such as an Apollo AP-3350B or AP-2250B, commercially available from Apollo (Zhuhai) Electronics Co., Ltd. Apollo Building, Lanpu Industrial Area E5 Jiuzhou Road, Zhuhai, China 519070, is mounted within peripheral enclosure 210, such that a reading surface 232 of the sensor 230 extends outside of the enclosure 210 and the back 234 of the sensor, having electrical contacts 236 thereon, lies within the enclosure 210. Reading surface 232 includes one or more sensing regions 238 connected to contacts 236. hi accordance with a preferred embodiment of the present invention, a flat cable and connector assembly 240 is provided having a plurality of conductors 242 disposed in a conductor plane 244 and preferably having a pair of protective wire grids 246 and 248 disposed in respective planes 256 and 258 located on respective opposite sides of the conductor plane 244. The flat cable and connector assembly 240 includes a connector portion 260 preferably including plural plated-through contact apertures 262 for electrical connection to respective ones of contacts 236 and a pair of plated-through ground contact apertures 264 for electrical connection to respective ground contacts 216.
The connector portion 260 is electrically connected to electrical contacts 236, which extend through apertures 262, preferably by soldering, thereby establishing an electrical connection between the sensor 230 and at least some of conductors 242. Others of conductors 242, designated by reference numerals 266, are preferably coupled to ground by being soldered to respective ground contacts 216. It is a particular feature of the present invention that, as seen in Fig. 2, a portion 270 of the flat cable and connector assembly 240 is arranged in a doubled-over configuration over the output contacts 236, thereby providing enhanced anti-tampering protection thereto. It is a further feature of the present invention that doubled-over portion 270 is located within the peripheral enclosure 210, which functions as an anti- tampering enclosure. Alternatively, the peripheral enclosure 210 may be eliminated and the doubled-over portion 270 is peripherally surrounded by epoxy, thus defining an alternative peripheral enclosure.
In accordance with a preferred embodiment of the present invention, as seen in Fig. 2, protective wire grid 246 extends over doubled-over portion 270. Grids
246 may be coupled to a magnetic head assembly tamper detection and disabling circuit
280. Additionally or alternatively one or more of conductors 242, here designated by reference numeral 284, which are not connected to electrical contacts 236 or ground contacts 216, are also coupled to tamper detection and disabling circuit 280. Circuit 280 is operative to erase encryption keys or other sensitive data upon sensed tampering with grid 246 and/or conductors 284.

Together with grid 246, grid 248 provides anti-tamper protection to the remainder of the flat cable and connector assembly 240. Preferably a layer 290 of epoxy is provided over doubled-over portion 270 within the enclosure 210, thereby providing a mechanically sealed, tamper-protected assembly. Various types of suitable tamper detection and disabling circuits 280 are described in the following patent publications, the disclosures of which are hereby incorporated by reference: U.S. Patent Nos. 5,998,858; 5,861,662 and 6,917,299.
Reference is now made to Figs. 3 A - 3 G, which illustrate the manufacture of the magnetic head of Figs. 1 & 2. Figs. 3 A and 3B show enclosure 210 associated with the mounting element 202. Preferably enclosure 210 is integrally formed with the mounting element 202. Alternatively it may be a separate piece which is joined to the mounting element 202. As a further alternative, it may be provided as part of sensor 230 in a customized version thereof.
