Abstract

A double keyboarded entry terminal for use in entering money transactions between customer and vendor in conjunction with a central computer, banks, and credit card companies, with physical and/or electronic security features which preclude access to secret coded entries by customer and vendor, one from the other, and collectively, from third party "visual eavesdroppers." Security features include physical screening as well as mechanical and electronic realignment of numeric key entry functions.

Claims

1. A keyboard terminal for use with a central computer whereby money transactions between a vendor and customer may be electronically completed via the collective keyboard entries made by vendor and customer comprising, first and second discrete keyboards for respective use of vendor and customer, said keyboards extending oppositely from a raised central display device housing discrete displays on respective opposite sides thereof for respective viewing by vendor and customer, each of said first and second keyboards comprising a plurality of function activating keys and a plurality of numeric entry keys, the depressible upper portion of at least each said numeric entry key comprising a visible display means for identifying the associated key function, with said display means being recessed within the associated keyboard surface to limit readability thereof only within a restricted angular field of view from vertical;

said numeric entry keys arranged adjacently to form a predetermined geometric pattern;

said numeric entry keys being physically aligned for depression contact of key carried probe means with an underlying connector matrix for generation of a related code word output definitive of that key function;

means to realign said key numeric entry functions comprising means for physically moving one or more numeric entry keys in the plane of the keyboard and within the confines of the geometric pattern collectively defined by said numeric entry keys.

2. The keyboard terminal of claim 1, wherein said numeric entry keys are arranged within the confines of a rectangular geometric pattern, each key being carried within a square housing, the sides of which slidably abut sides of adjacent ones of said housings, with the outer ones of said key housings being slidably abutted with a fixed wall means of said keyboard, the number of said numeric keys being at least one less than the number of key housings receivable within said fixed wall means.

3. A keyboard terminal for use with a central computer whereby money transactions between a vendor and customer may be electronically completed via the collective keyboard entries made by vendor and customer comprising, first and second discrete keyboards for respective use of vendor and customer, said keyboards extending oppositely from a raised central display device housing discrete displays on respective opposite sides thereof for respective viewing by vendor and customer, each of said first and second keyboards comprising a plurality of function activating keys and a plurality of numeric entry keys, the depressible upper portion of at least each said numeric entry key comprising a visible display means for identifying the associated key function, with said display means being recessed within the associated keyboard surface to limit readability thereof only within a restricted angular field of view from vertical;

said numeric entry keys arranged adjacently to form a predetermined geometric pattern;

said numeric entry keys being arranged in a fixed position within said predetermined geometric pattern;

means to realign said key numeric entry functions comprising means connecting a predetermined discrete binary code input to each of four key carried probe means carried by each of said keys, an underlying connected matrix with which said key carried probe means are engageable upon key depression, said display means of each of said numeric entry keys comprising an electronic numeric readout device, and means connecting said discretement binary code on each of said numeric entry key probe means to the electronic numeric readout device associated with that numeric entry key.

4. The keyboard terminal of claim 3 with means for selectively applying predetermined different permutations of said numeric entry key input binary codes to the probe means of said plurality of numeric entry keys.

5. The keyboard terminal of claim 3 with means for randomly sequencing the permutations of said numeric entry key input binary codes to the probe means of said plurality of numeric entry keys.

6. A keyboard terminal for use with a central computer whereby money transactions between a vendor and customer may be electronically completed via the collective keyboard entries made by vendor and customer comprising, first and second discrete keyboards for respective use of vendor and customer, said keyboards extending oppositely from a raised central display device housing discrete displays on respective opposite sides thereof for respective viewing by vendor and customer, each of said first and second keyboards comprising a plurality of function activating keys and a plurality of numeric entry keys, the depressible upper portion of at least each said numeric entry key comprising a visible display means for identifying the associated key function, with said display means being recessed within the associated keyboard surface to limit readability thereof only within a restricted angular field of view from vertical;

said numeric entry keys arranged adjacently to form a predetermined geometric pattern, said numeric entry keys being arranged in a fixed position within said predetermined geometric pattern;

means to realign said key numeric entry functions comprising means connecting a predetermined discrete binary code input to a key carried electronic numeric readout device, each of said keys carrying a probe means, an underlying connector matrix with which said key carried probe means are selectively engageable upon key depression, and gating means receiving the predetermined discrete binary codes inputted to said key readout devices and receiving a matrix generated enabling input to gate the instantly assigned binary code for a key to a common output upon that key being depressed for associated probe contact with said connector matrix.

7. The keyboard terminal of claim 6 with means for selectively applying predetermined different permutations of said numeric key input binary codes to the respective readout device and gating means associated with each key.

8. The keyboard terminal of claim 6 with means for randomly sequencing the permutations of said binary code inputs as applied to said key readout devices and associated gating means.

9. A keyboard terminal for use with a central computer whereby money transactions between a vendor and customer may be electronically completed via the collective keyboard entries made by vendor and customer comprising, first and second discrete keyboards for respective use of vendor and customer, said keyboards extending oppositely for respective viewing by vendor and customer, each of said first and second keyboards comprising a plurality of function activating keys and a plurality of numeric entry keys, means to effect realignment of the entry function of at least one numeric entry key by moving that key in the plane of the numeric entry keys, and means for physically screening the respective key entry activity of said vendor and customer, one from the other.

10. The keyboard terminal of claim 9 with said means for physically screening comprising a raised, centrally oriented, and at least partially hooded, double-sided display device, each side of said display being restricted to display readout of key entry activity made only on the keyboard on that side of said terminal.

11. The keyboard terminal of claim 10 with the keys in the respective vendor and customer keyboards carrying key function identify display means physically oriented for readability thereof within a restricted viewing angle.

12. The keyboard terminal of claim 9, with means to realign the entry function of at least one numeric entry key moving that key in the plane of the keyboard.
