Abstract:
A process for maintaining financial records, such as checkbook balances, in which a checking account user employs a hand-held calculator to record the usual checkbook data electronically. The calculator is programmed to calculate and memorize a first running balance dependent upon numeric data entered by the user. A financial institution maintains a second running balance dependent upon the user&#39;s checks and deposits and periodically provides the user with a magnetic card on which the second running balance and other data have been recorded. The card is read by the user&#39;s calculator to balance the user&#39;s checkbook.

Description:
BACKGROUND OF THE INVENTION 
     This invention relates to the maintenance of financial records and is more particularly concerned with a process for recording, balancing, and rectifying data normally maintained in a checkbook. 
     State-of-the-art technology exists for recording checkbook data electronically, and even for electronic check writing. See, for example, U.S. Pat. Nos. 4,222,109, issued Sept. 9, 1980; 4,308,588, issued Dec. 29, 1981; and 3,920,979, issued Nov. 18, 1975. Personal portable terminals for financial transactions are also known. See, for example, U.S. Pat. No. 4,277,837, issued July 7, 1981. It has also been proposed to substitute for a conventional passbook (that requires passbook printing machines) a &#34;card&#34; that is capable of providing the same functions of a passbook plus some features of an ordinary calculator. The &#34;card&#34; is coupled to a card reader of a separate processing unit to transfer data thereto. See Japanese Pat. No. 56-14369. However, despite the ready availability of sophisticated hardware and software for conducting a plethora of financial transactions, the ordinary task of monthly checkbook balancing and rectification remains inordinately difficult and tedious. In fact, the task of comparing a balance of checks and deposits as recorded on a bank statement with a checkbook balance is so burdensome that many users of checking accounts simply accept the bank statements as correct and ignore any discrepancies. The present invention provides a simple process for solving this problem. 
     BRIEF DESCRIPTION OF THE INVENTION 
     In a preferred embodiment of the invention, checkbook stubs are eliminated, and the handwritten data normally recorded therein is entered into a memory of a hand-held calculator. The calculator is pre-programmed to compute and record a first running balance from the data entered. Instead of sending the usual bank statements to checking account users, a bank or other financial institution responsible for disbursing and receiving funds corresponding to transactions entered in the hand-held calculator sends to the checking account user a machine-readable record, such as a magnetic card on which the usual bank statement information is recorded. The user inserts the card into the calculator, which is pre-programmed to compare the first balance in the calculator memory with a second balance on the card and to assist the user with the rectification of any discrepancies. The tedious task of balancing a checkbook and rectifying any differences between the checkbook balance and a bank statement balance is eliminated. 
     In one of its broader aspects, the invention is a process of maintaining financial records, which comprises providing a user with a unit having data entry means, memory means, and calculating means, entering into said memory means, via said data entry means, machine-readable data, including numeric data, concerning each of a plurality of financial transactions of the user, calculating, via said calculating means, and storing in said memory means a first running balance depending upon the totality of said numeric data, providing data, including numeric data, concerning said financial transactions to a remote financial institution, providing at said financial institution a machine-readable record of a second running balance dependent upon the totality of the numeric data provided to said financial institution, electronically comparing, from time to time, said first running balance in said memory means with said second running balance in said record, and displaying the results of said comparing. 
    
    
     BRIEF DESCRIPTION OF THE DRAWING 
     The invention will be further described in conjunction with the accompanying drawing, in which the single FIGURE is a perspective view illustrating, somewhat diagrammatically, a hand-held calculator and magnetic card employed therewith in accordance with the invention. 
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A preferred embodiment of a process in accordance with the invention will be described with reference to preferred apparatus for performing the process of the invention, particularly for the maintenance of checkbook financial records, but the invention has broader utility. In accordance with the invention, each user of a checking account is provided with a hand-held calculator, such as the unit 10 shown in the drawing. The calculator may have a set of alphanumeric keys 12 and a display 14 (such as an LCD display). Alphanumeric data normally entered on checkbook stubs to record check writing and bank deposit transactions is instead entered into the calculator via the keys 12, or alternatively via voice signals (a microphone input being indicated at 16). The hand-held calculator has sufficient memory to retain the entered data and the results of calculations to be described. The calculator is pre-programmed to record the data entered and to compute from the numeric data a running balance representing the net of check writing and bank deposit transactions. Information concerning the various transactions and the running balance can be called up by appropriate key strokes and displayed. The hand-held calculator has a self-contained power source, such as long-lasting or rechargeable batteries, or solar cells 17, and may also be energized by an AC to DC converter. The memory, which must have sufficient storage capacity as noted above, may be magnetic or semi-conductor, for example. The calculator has conventional hardware and software for processing and recording data digitally, as is well known in the art. In the preferred form, the calculator is also capable of reading data recorded magnetically on cards (so-called &#34;magnetic cards&#34;). One such card 18 and a slot 20 for receiving the same are illustrated in the drawing. Apparatus based upon the technology embodied in the Hewlett-Packard 71B programmable calculator with the 82400A Card Reader may be employed in the invention, although it will be apparent that the sophisticated computations of which this apparatus is capable are not required by the invention. Magnetic tape cassettes may also be employed as the memory of the calculator (and as a bank statement recording medium) for use with suitable recording and playback units, such as the Sharp EL 5500II provided with the CE-126P Printer/Cassette Interface and a cassette recorder. 
     In the preferred embodiment the responsible financial institution maintains records of the checks that clear and deposits that are made and periodically sends to the checking account user a magnetic card 18 on which has been recorded the same type of information that normally would be provided in a bank statement. A secret personal identification number (PIN) may be recorded on each magnetic card so that only the corresponding checking account user may have access to the recorded data. 
     To check the accuracy of the running balance held in memory in the hand-held calculator, the user inserts the magnetic card 18 into slot 20 of the calculator 10 and instructs the calculator (by appropriate key strokes) to read and process the data on the card. The calculator is pre-programmed to compare data on the card with data previously entered by the user. The check number may be employed as a sort parameter. The calculator displays any disagreement as to check amounts, checks not entered or not cashed, etc., subtracts any monthly service charge, makes any necessary corrections to the balance, and displays the corrected balance. These calculations can be completed within a few seconds. If desired, all of the data held in the memory of the calculator, including the results of any calculations, may be read out to a printer through a conventional output port. The following is a typical flow chart which may be employed to implement the process of the invention.

     While a preferred embodiment of the invention has been shown and described, it will be apparent to those skilled in the art that changes can be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims. For example, the &#34;check stub&#34; data may be recorded on magnetic cards by the hand-held calculator, and the cards may be transported to the responsible financial institution, as by mailing the card to a bank office or carrying the card to an automatic teller machine, at which the card is read and calculations performed electronically for checking account balancing and rectification.
