Abstract
The utility model relates to a password input device, which comprises a body internally provided with a circuit, and a plurality of keys arranged on the body. The password input device is characterized in that a plurality of keys are respectively provided with LED digital display tubes connected electrically with the circuit in the body. When a user prepares to input the password, the password input device displays figures 0-9 randomly on each key. The password input device of the utility model has the advantage of simple structure and can effectively prevent others from peeping at the password.
Description
Technical field
The utility model relates to a kind of PIN PAD, relates in particular to a kind of structure of PIN PAD of stochastic transformation number.
Background technology
Current society, increasing place needs people to input password.From POS machine bankcard consumption, the ATM enchashment is to bank counter business or the like.Password has also brought simultaneously some potential safety hazards easily bringing people, and wherein topmost is exactly that password is revealed.No matter common password entry terminal is on the POS machine ATM, though certain peep-proof measure is all arranged, but can't fundamentally eliminate.Because its numeral is fixed on the button, so the bystander just is easy to judge password in the position that the importer points as long as see from the side.
The utility model content
The purpose of this utility model provides a kind of simple in structure and can effectively prevent the PIN PAD that other people peep.
For achieving the above object, the solution that the utility model adopts is: a kind of PIN PAD, it comprises that inside is provided with the body of circuit and is arranged on plurality of keys on the described body.Described plurality of keys respectively is provided with LED digital display pipe, and described LED digital display pipe is electrically connected with circuit in the body.When the importer prepared to input password, PIN PAD can be shown to 0～9 these 10 digital Random assignments on each button.
PIN PAD described in the utility model embeds seven segmentation LED digital display pipes on button, and is connected with internal circuit on the body.Each button all can show 0～9 different numeral.In the time will inputing password, input unit can be assigned randomly on each button 0～9, so, even other people see that finger position also can't know password.
Description of drawings
Fig. 1 is the side view that meets PIN PAD of the present utility model; Fig. 2 is the front elevation that meets PIN PAD of the present utility model; Fig. 3 is the structural representation of the button of PIN PAD shown in Figure 2.
Below in conjunction with accompanying drawing the utility model concertina type PIN PAD is further specified.
Embodiment
Fig. 1 to Fig. 3 has disclosed and has met PIN PAD 1 of the present utility model.Described PIN PAD 1 is manual button, and it comprises that inside is provided with the body 11 of circuit (not shown) and is arranged on plurality of keys 12 on the described body 11.
Described plurality of keys respectively comprises shell 121, merge module 122, reaches intermediate module 123.Described shell 121 is provided with the receiving space 120 of accommodating described merge module 122 and intermediate module 123.Described intermediate module 123 is pressed on the described merge module 122.Described merge module carries the LED digital display pipe 124 of display digit, and described intermediate module 123 is provided with and LED digital display pipe 124 corresponding grooves 125.Described LED digital display pipe 124 is seven segmentation LED digital display pipes 124.When described seven segmentation LED digital display pipes 124 were luminous, light can pass from groove 125.The upper surface of the described relatively button 12 of described groove 125 has certain depth, makes when LED digital display pipe is luminous, has only from importer's positive angle and just can see.
In meeting other embodiment of the present utility model, button (not shown) can be packaged in the formula that wherein is made of one with the merge module (not shown) of carrying LED digital display pipe (not shown).In addition, button (not shown) can also be combined by first module (not shown) of carrying LED digital display pipe and second module (not shown) of offering groove.
Described PIN PAD 1 also is provided with on its body 11 confirms button 13.
The service support equipment that PIN PAD 1 described in the utility model needs is the same with existing ordinary password input unit, can substitute the ordinary password input unit and be widely used in the various occasions that need PIN PAD.Scrambler 1 described in the utility model embeds seven segmentation LED digital display pipes 124 on button 12, and is electrically connected with the circuit of body 11 inside.Each button 12 all can show 0～9 different numeral.In the time will inputing password, this PIN PAD 1 can be assigned randomly on each button 12 0～9, and described seven segmentation LED digital display pipes 124 embed darker, can see just that from the importer from positive angle numeral arranges thereby guarantee to have only, so, even other people see that finger position also can't know password.
When the numeral input password that the importer shows on according to button 12, finish press confirm button 13 after, the numeral that shows on the button 12 disappears thereupon, in case other people know that button arranges, thereby obtains password.
The above only is a kind of embodiment of the present utility model, it or not whole or unique embodiment, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model instructions is claim of the present utility model and contains.
