DE10338955A1 - Check-card sized device for storing number combinations, especially PINs, has pull out strips on which a user writes his PINs so that they will only be in a correct sequence with a special master PIN is correctly displayed - Google Patents

Abstract

Check-card sized device for making a note of character combinations, especially PINs or passwords. The device has mechanical encryption and decryption means. It comprises number strips that are pulled out and used to store a number of PINs. the card is operated by selecting a master pin and then manually recording other PINs or passwords by writing values that will occur in windows next when the master PIN is displayed in the master PIN window.

Description

Anyone has to remember today PINs for his ec card, number combinations for locks like electronic door locks, combination locks for briefcases or bicycles, Lock codes for Car radios, mobile phones or even passwords for telephone banking, online banking or others Types of PC and Internet use.

The Problem of the user here is the large number to be noted of these codes and the loss of security and warranty of the Banks, if unencrypted be noted.

The The present application relates to a device having the possibility opened, multiple PINs and passwords to record and encrypt. she is preferably carried out in the format of a check card, so that they come from the user along with the check cards in the corresponding Pocket of the purse or wallet can be.

construction

The Device consists of a three-layer construction, preferably in Bank card format, wherein in the simple embodiment of the device, the lower Location is executed only in the function as the lower cover page. Another embodiment this device is by attaching a compared to the top vertical axisymmetric mirrored arrangement of the window openings on the bottom also on the back usable. This results in a doubling of the number of notable PINs and passwords.

The middle position of the device ( 1 ) consists of the number strips ( 1 No. 1) with the associated extension-limiting webs ( 1 No. 2) and the frame with the guide webs for the digit strips ( 1 No. 3). On one side of the digit strips are pre-printed numbers in ascending or descending order ( 1 No. 4). The numbers, letters or signs ( 1 No. 5) are manually attached by the user as described below.

The upper layer of the device ( 2 No. 1) contains the labeling fields for the use of PINs or passwords ( 2 No. 2), in which by the user eg the account number of the ec card or the term "cell phone", "Briefcase", etc. is entered, for which the corresponding PIN applies. This location also contains the windows for displaying the master PIN ( 2 No. 3) and the windows for manual entry and display of the PINs ( 2 No. 4).

At the location where the grips of the digit strips are located, a recess (at all three layers of the device) is ( 1 No. 6), which allows the numeric strips to be inserted flush into the device. This allows on the one hand, the compliance of the check card format of the entire device and on the other it serves for security after using the device, as this fits again in this state in the check card slot of the purse or wallet, which is accompanied by an adjustment of the digit strips, which again the Encryption of PINs and passwords generated.

Thereby, that the three-layer structure of the device by means of relatively thin plastic film feasible, there is the possibility the device in a larger format as that of a bank card and folding by credit card format bring to. Another embodiment of this Device is thus both vertical and horizontal Foldable direction. The unfolding of the device resulting larger area increases the number Noticeable PINs and passwords.

function

The user thinks of a freely selectable master PIN and sets this by appropriate positioning of the digit strips by pulling or pushing in on the designated handles ( 2 No. 5) on the windows of the master PIN display ( 2 No. 3). He then labels the labeling fields for the use of the PINs or passwords ( 2 No. 2) eg with the account number of the ec card or with the term "cell phone", "Briefcase" etc. Then he labels the number strips, which are displayed via the windows of the PIN display ( 2 No. 4), with the digits of the respective PIN or with the letters or characters of the respective passwords. If shorter PINs or passwords are to be noted, than labeling fields are available for this purpose, the free fields can be left justified or left-aligned or with fill characters such as dots, dashes or similar. be labeled. For security reasons, however, it is advisable to also fill the empty fields with corresponding numbers, letters or characters. In this case, however, the user must remember the number of digits of the PIN and whether he has entered the PIN right-justified or left-justified.

If longer PINs or passwords are to be entered than places are available, it is possible to make the entry in two or more lines. That is, in the upper line, the entry of the characters or digits of the first part of the PIN or the password and in the line (s) below it the entry of the remaining part.

The user then labels the remaining free fields of the random-digit number strips by shifting each number strip by one position and thus creating the empty labeling fields in the windows of the PIN display ( 2 No. 4). This is necessary in order not to limit the number of encryption options (higher security) by the exclusive presence of authentic PIN digits.

Then pushes He again the number strips to the stop. The ad The authentic PINs will disappear.

If he needs a PIN at a later date, he sets the digit strips such that the master PIN that he memorizes becomes visible in the corresponding windows. All PINs or passwords can now be stored unencrypted in the PIN display windows ( 2 No. 4).

To In this process, the user pushes the number stripe back up to stop in the device, on the one hand, the PINs again to make it disappear and on the other hand Put the device back in the compartment of the wallet or wallet to be able to.

Claims (3)

Credit card-sized device for recording and mechanical encryption and decrypting Number combinations (PINs) and passwords, consisting of movable Number strip already labeled for setting the master PIN are and the number of the maximum number of digits of the PINs and passwords results and on which the entry of the PINs or passwords and the filler character done manually. Further comprising a top with window cutouts, the only relevant to the display or label fields of these digit strips release and having a recess for sinking the handles the number strip. Further comprising a lock function, the a plugging this device into the bank card slot of the wallet or Wallet without prior encryption of PINs or passwords prevented. Device according to claim 1, characterized in that that they through - im Comparison to the top - vertical axially symmetrical mirrored arrangement of the window sections on the bottom also on the back is usable and thereby doubling the number of notable PINs and passwords he follows. Device according to claim 1, characterized in that that they are both vertical and horizontal is collapsible and thus by the resulting when unfolding larger area of the Device the possible Number of notifiable PINs and passwords is increased.
