ABSTRACT:
A backing plastic for a carbon-style checkbook is provided with a stylus sensor to sense the position of a writing instrument as a check is written. The position of the writing instrument is input to a microcomputer that calculates beginning and ending vectors for each written character to decipher its identity. The amount of the check is then subtracted from the checkbook balance, which is updated and permanently stored. The amount of each of a checkbook of checks is also permanently stored and an attachment provided to allow a check register to be printed out on a standard computer printer. A beginning-and-ending-vector system of number recognition allows for recognition of a wide range of writing styles within certain basic limits. Nonrecognition is signified by an audible tone after which the numbers may be retraced with slightly more care, if necessary, to allow for recognition. Checks may be voided by scratching out the written amount. Deposits and periodic interest payments may be entered in like manner using deposit slips provided with the checkbook. The microcomputer is provided with a keyboard and display and may also serve as a checkbook calculator.
