US4532416A — Transaction terminal with simplified data entry

Claim 1

Independent Claim 138 words

A transaction terminal comprising a reader to read data from any one of a plurality of suitably encoded cards, a keyboard, and a data processor receiving data and storing data from said reader and said keyboard, said data processor having an operating mode and at least one supervisory mode, and said cards being of at least three classes, each being encoded with a different class of data recognizable to the processor, the processor being responsive to data on cards of a first class to enable it to enter said at least one supervisory mode, and being controlled jointly by data from the keyboard and data from cards of a second class in said operating mode, and being controlled jointly by data from the keyboard and data from a third class of cards in at least one supervisory mode.

Claim 2

Dependent Claim 138 words

A transaction terminal comprising a reader to read data from any one of a plurality of suitably encoded cards, a keyboard, and a data processor receiving data and storing data from said reader and said keyboard, said data processor having an operating mode and at least one supervisory mode, and said cards being of at least three classes, each being encoded with a different class of data recognizable to the processor, the processor being responsive to data on cards of a first class to enable it to enter said at least one supervisory mode, and being controlled jointly by data from the keyboard and data from cards of a second class in said operating mode, and being controlled jointly by data from the keyboard and data from a third class of cards in at least one supervisory mode.

Claim 3

Dependent Claim 24 words

A terminal according to claim 1, including at least one card of said first class and a plurality of cards of said third class.

Claim 4

Dependent Claim 42 words

A terminal according to claim 2, wherein the cards of said third class are encoded with data readable by said reader and such as to change the data stored by said processor such as to alter its operations in its operating mode.

Claim 5

Dependent Claim 45 words

A terminal according to claim 1, including at least one of an alphanumeric printer and an alphanumeric display, wherein the data encoded on cards of the third class comprises alphanumeric messages to be displayed or printed on at least one of said printer and display.

Claim 6

Dependent Claim 15 words

A terminal according to claim 4, wherein the keyboard is a numeric and functional keypad.

Claim 7

Dependent Claim 16 words

A terminal according to claim 5, including a second keyboard usable alternatively to the first keyboard.

Claim 8

Dependent Claim 24 words

A terminal according to claim 6, wherein the second keyboard forms part of a portable keyboard unit separable from the remainder of the terminal.

Claim 9

Dependent Claim 61 words

A terminal according to claim 7, wherein the portable keyboard unit further comprises a memory, a power supply, control logic operative to display keyboard entries on the display and store them in the memory, and an interface to transfer data from the memory to the remainder of the terminal when the keyboard unit is assembled to the remainder of the terminal.

Claim 10

Dependent Claim 140 words

A transaction terminal comprising a reader to read data from suitably encoded credit cards, a main keyboard, a main display for displaying information including data entered through the keyboard, a printer, a data processor receiving data from said reader and said at least one keyboard, and a program memory containing selectable programs for operating said terminal in a plurality of modes in at least one of which it receives data from said credit card reader, wherein the terminal further includes a portable keyboard detachable from the remainder of the terminal and operable when attached to receive a data entry required to enable said at least one mode, at a point remote from the remainder of the terminal and operable to transfer it to the processor independently of the main keyboard and display when reunited with the remainder of the terminal.

Claim 11

Dependent Claim 140 words

A transaction terminal comprising a reader to read data from suitably encoded credit cards, a main keyboard, a main display for displaying information including data entered through the keyboard, a printer, a data processor receiving data from said reader and said at least one keyboard, and a program memory containing selectable programs for operating said terminal in a plurality of modes in at least one of which it receives data from said credit card reader, wherein the terminal further includes a portable keyboard detachable from the remainder of the terminal and operable when attached to receive a data entry required to enable said at least one mode, at a point remote from the remainder of the terminal and operable to transfer it to the processor independently of the main keyboard and display when reunited with the remainder of the terminal.

Claim 12

Dependent Claim 54 words

A terminal according to claim 9, wherein the portable keyboard unit comprises a memory, a power supply, control logic operative to store keyboard entries in the memory, and an interface to transfer data from the memory to the remainder of the terminal when the keyboard unit is assembled to the remainder of the terminal.

Claim 13

Dependent Claim 29 words

A terminal according to claim 9, including a plurality of portable keyboard units any one of which may be used to transfer data to the remainder of the terminal.

Claim 14

Dependent Claim 84 words

A terminal according to claim 10, including an encryptor, wherein the program memory includes a program for operating said terminal in a transaction mode in which it is configured as part of a transaction sequence to input a Personal Idenfication Number transferred to the processor from the portable keyboard unit to the encryptor, and to compare an encrypted code from the encryptor with an encrypted Personal Identification Number code received from the card reader, and to continue a transaction sequence if the codes coincide.

Claim 15

Dependent Claim 58 words

A terminal according to claim 12, wherein the program memory includes a program for operating said terminal in an encryption mode in which it is configured successively to receive a Personal Identification Number transferred to the processor from the portable keyboard unit, to input that number to the encryptor to form a code, and to output that code.
