Description

A kind of portable bank card number password storage machine

Technical field

The present invention relates to a kind of portable bank card number password storage machine.

Background technology

In the last few years, for improving service level, the management level of bank, enhance the bank's image, and saved the personal expenditures spending, each specialized bank drops into a large amount of ATM and uses.But as the precision equipment of a kind of round-the-clock, unmanned, outdoor application, the ATM device of withdrawing the money also exists many potential safety hazards.

We always can hear on various medium or see that the money that someone deposits bank in has disappeared suddenly, and someone bank book/clip pin is stolen, makes people produce distrust to bank, or even suspects.With I also often can hear such as I.D. lose, bank book/card loses, forgets Password or the like, these things are innumerable, I believe it almost is that everyone lives through.In case take place gently then let you are busy for a moment, make up various certificates and card, heavy then just be gone for ever, but no matter be gently or weight, always last result lets you feel to feel exhausted.What so this result cause because of? After all, below 2 be of paramount importance: the one, certificate is lost and to be limited by everywhere, must make up; The 2nd, bank book/card is lost the loss that possibly cause economically; Must in time report the loss, yet at home, most of banks need provide perfect instrument when reporting the loss; So just there is a vacuum time section; During this period, the offender has taken advantage of with regard to organic, causes user's unnecessary loss.

We can be without bank card, bankbook; Do not need password yet; Only fingerprint or the face with oneself scans; Can just on the self-service machine of bank, easily accomplish financial business such as paying the fees, transfer accounts? This is not the scene in the science fiction sheet, and the people in the reality also soon can enjoy this facility.Since 2006 1 January, 700 co-net points of Beijing rural commerce bank were just laid thousand fingerprint self-help bank equipment comprehensively.The inductor that an identification fingerprint is arranged on the self-help charging terminal of fingerprint bank is as long as above being placed on finger, system will discern and access client's information automatically, also can accomplish various fee payment services without plug-in card.But this needs the client to carry out the finger print information collection to bank in advance, and accounts information and the fingerprint of oneself are bound.Start the drawback of having described many cryptographic systems at article, and fingerprint recognition system can remedy all, and be easy.If used fingerprint identification technology, the probability of the stolen generation of that bank card bankbook/clip pin is almost nil; If used fingerprint identification technology, that is no matter whether certificate is lost, and fingerprint can not be lost, so report the loss being a thing easily, does not even need artificial interference; If used fingerprint identification technology, can stop the possibility that credit card is duplicated, because there is not corresponding fingerprint, all will be safe.　

A things is to have two faced all the time.Realize this fingerprint bank, need cost great amount of manpower and material resources and energy to go to design and dispose corresponding link, the finger print information of optical storage a large number of users and bank card information are just

Be a very loaded down with trivial details job, and this has been meant also that probably line silver is capable since 06 year carries out in Beijing rural commerce bank and fail the main cause popularized in each big bank.

But the application of fingerprint identification technology in bank well enlightens for us, and I have designed a kind of " fingerprint bank " of simplifying pattern---personal bank card information stores machine at this.As a kind of portable equipment, this machine is provided with startup password, and the user is through fingerprint identification module identity verification and inquiry or modification user's bank card and encrypted message behind the input password, and encrypted message shows with * number.Startup password, finger print information all can be provided with when using for the first time.This machine is connected the back with ATM only need to select the card number inquiry business of grade of transferring accounts of can directly withdrawing the money; Need not to input password when carrying out banking; Therefore can greatly improve the security when carrying out banking, and this device just stores a spot of fingerprint and bank card information through ATM, little to designing requirement; Therefore cost is not high yet, is convenient to be popularized for each family or individual.

Summary of the invention

The object of the present invention is to provide a kind of portable bank card number password storage machine.

The technical scheme that adopts is:

A kind of portable bank card number password storage machine mainly comprises data input module, display module, fingerprint identification module, data processing module, data transmission module, system reset and seven modules of clock circuit, system

Data input module: form by 4 * 4 keyboards, be used to import information such as account number cipher and handle to processor.

Display module: form by a LGM12641BS1R LCD LCD MODULE and a slice 74HC245 three-phase latch, can export numeral and Word message, show by the account number cipher of keyboard input or the information such as number of the account of storage through it.

Data transmission module: form by a slice MAX232 and RS232, be used for the data transmission between processor and the host computer.

Fingerprint identification module: be made up of a MBF310 fingerprint sensor, induction finger print information output digital signal is to controller.
