Abstract
The invention discloses a numeric keyboard capable of randomly changing distribution sequence of numeric keys and relates to the technical field of information, in particular to the numeric keyboard of information technology products. The numeric keyboard mainly comprises a base, a liquid crystal display panel, ten numeric keys capable of displaying 0-9 single figures, a microprocessing chip for controlling the display sequence of the numeric keys and processing key signals and an ordinary/dynamic key, a clear key and a confirmation key, wherein the ordinary/dynamic key, the clear key and the confirmation key are used for changing displaying sequences of the numeric keys between sequent distribution and random distribution. The numeric keyboard is characterized in that the dynamic keyboard function can be achieved by randomly changing the displayed numerical values of the ten numeric keys capable of displaying the 0-9 signal figures so as to change the distribution sequence of the 0-9 numeric keys. The numeric keyboard can be used in bank card imprinters, automatic teller machines (ATMs), bank terminals and points of sales which need password entering so as to improve peeping-resisting capability during password entering and improve personal financial security.
Description
Technical field
The present invention relates to areas of information technology, particularly the data entry keyboard of IT product.
Background technology
The arrangement position of numerical key 0-9 on the cipher inputting keyboard of the equipment such as existing bank card machine for punching the card, ATM, banking terminal machine, POS machine is fixed, unique people can input according to the user gesture snooping password information of password, thereby jeopardizes personal finance safety.
Summary of the invention
But the technical matters that the present invention mainly solves is to provide the numeric keypad that a kind of randomly changing numerical key puts in order, can before user input data, allow the randomly changing that puts in order of numerical key, increase the difficulty of peep of cipher, strengthen personal finance safety.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: but the numeric keypad that provides a kind of randomly changing numerical key to put in order mainly comprises: base, display panels, ten can show the 0-9 individual digit numerical key, for control figure key DISPLAY ORDER and process push button signalling micro-chip processor, in order, arrange and random alignment between switching numerical key DISPLAY ORDER common/dynamic key, clear key, acknowledgement key, output interface.It is characterized in that: the shown numerical value of numerical key that can show the 0-9 individual digit by ten of randomly changings changes putting in order of ten key, thereby realizes the function of dynamic keyboard.
Described display panels is for showing the numeral of inputting by numerical key, described numerical key is for inputting the numerical value of 0-9, described micro-chip processor is for control figure key DISPLAY ORDER and process push button signalling, described common/dynamic key in order, arrange and random alignment between switching numerical key DISPLAY ORDER, described clear key is for removing the numeral of input, described acknowledgement key is for confirming whole numerals of inputting, and described output interface is for exporting to main frame or equipment the numerical value of inputting on numerical key.
Described micro-chip processor is connected with display panels, numerical key, common/dynamic key, clear key, acknowledgement key, output interface respectively.
Described numerical key comprises miniature display screen and touch-switch, with micro-chip processor, is connected respectively.Described miniature display screen is for showing the numeral of 0 to 9, and described touch-switch is for selecting numerical value shown on miniature display screen by button.
Described common/dynamic key in order, arrange and random alignment between switching numerical key DISPLAY ORDER.When order was arranged, the numerical value that the miniature display screen of numerical key shows was 1-9 and 0 from top to bottom, left to right.When random alignment, by micro-chip processor, produce the random number formed by ten different digitals of 0-9, the corresponding numerical key of bits per inch value, press from top to bottom, left to right and show on the miniature display screen of numerical key.
Described micro-chip processor, is presented at rank results respectively on the miniature display screen of 10 numeric keys 0-9 ten number random alignment from top to bottom, left to right one by one by built-in program.
The accompanying drawing explanation
Fig. 1 is module diagram of the present invention.
