Description

Bank CPU card POS

The present invention relates to a kind of checkout of bank.

In the prior art field, bank can only be to collect money the same day to send paying receipt in second day when doorstep fee-collection service, and there are the following problems:

1, can't supervise and prevent bank's inside crime of cashier of calling, as temporary river closure, appropriate public funds for personal use falsified accounts, corruption etc.;

2, can't accomplish the cashier with money is clear face to face, account is clear by payee, easily produce dispute;

3, gathering finishes to the doorstep, after the cashier gets back to bank, need to check by pen again, and typing Bank Clerk system, the duplication of labour again, workload is big.

The objective of the invention is to design has tight antiforge function, also has the emergent gathering functions of the cabinet of facing, a bank CPU card POS easy and simple to handle.

In order to achieve the above object, the technical solution used in the present invention is:

The bank CPU card cash collecting system of calling is made up of card sending system, authenticator, cashing machine and data entry system four parts, and core is a CPU card cashing machine.

Before carrying out doorstep fee-collection service, at first to set the circuit of collecting money to the doorstep, which unit is promptly arranged in the gathering to the doorstep of same circuit, 1～2 cashing machine of a general line configuring, an authenticator is respectively joined by each payee.Before use, card sending system must be issued corresponding four kinds of CPU cards, and promptly 1) authenticator SAM card; 2) cashing machine SAM; 3) gathering card; 4) senior gathering card (promptly being responsible for card).Except that senior gathering card, the line number of the various cards that act on same circuit must be identical.In addition, before the gathering of calling, also must be with account number, organization, unit numbering, bank of deposit's name of payee, typing cashing machine.

Before carrying out doorstep fee-collection service every day, must be responsible for by bank and authorize, and set cashier teller number by being responsible for; Step is: at first make cashing machine energising, insert then and be responsible for card, behind key authentication, cashier teller number is set in prompting, extracts thereafter and is responsible for card, inserts the gathering card again, and makes it to enter master menu, and then extract this card, so just authorizes.Authorize each time, one day with interior effective.Licensing process does not allow outage, can fail otherwise authorize, and must heavily come.

When a certain unit collected money to the doorstep, the gathering card must authenticate earlier, and be about to the gathering card and insert the authenticator of payee, if authentication passes through, back four and payee's numbering of this authenticator display screen circuit number.The unit authenticator can't use for some reason, also can be authenticated with the method for typing electronics signature by the financial executive of unit.But the method for typing electronics signature, only after using once above authenticator, just effectively (gathering of same unit only need authenticate once in one day).

The cashing machine attaching plug is inserted electric main, and turn on the power switch, the cashing machine display screen shows: " welcome to use the CPU card cash collecting system of calling, please insert the gathering card " shows the current time simultaneously.When with senior gathering card (being responsible for card) insertion, (note direction of insertion, necessary chip is downward), if key authentication passes through, screen display after the several seconds then: " please import teller number: " if imported teller number in the past, then shows original teller number, otherwise show blank, press numerical key input teller number, after having pressed 8 numerical keys, teller's end of input enters master menu automatically, master menu has 9, shows by arbitrary key page turning.With senior gathering card, each function that can enter master menu, need not authentication with senior gathering card gathering.If insert common gathering card in original state, after then key authentication passes through, screen display: " please enter password: ", password length is 6, is arranged to " 123456 " when dispatching from the factory, if it is correct to enter password, then show master menu, incorrect as password, then can't enter master menu.With common gathering card,, before will blocking the insertion cashing machine, must earlier this card be inserted unit authenticator and authenticate, otherwise when entering the 4th of master menu " operation of collecting money ", can't collect money to the gathering of a certain unit.

Advantage of the present invention:

1) provides the safe and effective bank gathering means of calling

This CPU card cashing machine requires before calling gathering every day, must have the supervisor of bank to stick into supervisor Row is authorized, and is set the cashier's that called the same day teller number by supervisor; When collecting money to a certain unit, Also must be carried out identity validation to the cashier by payee, legal just permission of identity collected money.

2) operating function of collecting money simply, fast

Cashing machine has when gathering puts cleer and peaceful package gathering dual mode face to face, and card is inserted as long as the cashier will collect money Enter cashing machine, after key understanding was passed through, the cashier entered password again, imports then payee's account number, receipts Money kind and the amount of money etc. just can be finished the gathering operation.

3) print paying receipt

When the cashier ought pen gathering content input cashing machine, and confirm errorless after, the thump printing key just can print paying receipt apace, gives payee as paying voucher.

4) complement receipt function

If when printing receipt, when running into fault such as printer paper serious dislocation, no paper or paperboard, can carry out the complement receipt, during complement, the cashier is as long as key in the serial number of need complement receipt.Desire to enter complement receipt function, must two card operations.

5) towards orthofunction

The cashier is wrong as finding certain completed transaction, and is then available towards orthofunction, should just dash by pen, more correct transaction re-entered, and desires to enter towards orthofunction, also must two card operations.

6) statistical function

This cashing machine also has statistical function, can be automatically add up by the gathering kind, can show the gathering number of deals on the same day, and the collection amount aggregate-value is checked up aggregate-value face to face, collect money aggregate-value and roll up other aggregate-value of package.
