EZ-Change-Prompter display for cash drawers

      Disclosed is a display device for cash registers or
point-of-sale terminals that solves the problem of giving correct
change by providing an operator careful guidance and feedback during
each transaction as to the correct number of each type of coin and
bill to give to customers.

      Operators of cash registers, or point-of-sale terminals, often
make costly errors or have difficulty in giving customers the correct
change after they make a purchase.  (Change includes both coins and
bills.)  For example, a customer makes a purchase of $23.67, and
gives the operator a $50.00 bill.  How many coins and bills of each
denomination should the operator return to the customer?  Because of
high turnover rates, variable educational and cultural backgrounds,
and job stress, this question is often difficult for operators.
Automatic coin dispensers associated with cash registers solve this
problem for coins, but not for bills (which of course can lead to
more costly errors).  Automatic coin dispensers -- even for coins
only -- represent an expensive solution.  The device described here
presents a better solution to the problem.

      Description by example - One implementation of this EZ-Change
invention consists of a cash drawer attached to a cash register, said
cash drawer being instrumented with novel signal displays attached to
each coin and bill bin.  Each signal display is a bank of N on/off
indicators (e.g., light emitting diodes) and is connected to the cash
register's central processor.  Once a sales transaction is complete,
the central processor turns on combinations of indicators to give a
visual indication of how many coins and bills to dispense from each
bin.  The Figure shows one example of such a configuration with
indicators lit to guide an operator in how to dispense $7.43 change.
In this example, there are four indicators per display (N=4), but
this may vary depending on the monetary system or change-making
algorithms.

      Claimed is an instrumented cash drawer and point-of-sale
terminal (cash register) consisting of:

1.  A signal display associated with each coin and bill bin that can
    show a count from 1 to N.
2.  Denomination labels for each bin.
3.  Connections from displays to cash register central processor.
4.  Software in cash register central processor to control the signal
    displays to indicate numbers of each denomination necessary to
    make change based on the difference between a given sales total
    and the amount tendered.

      EZ-Change claims include any indication to the operator of the
correct configuration of different denominations to give to the
customer in change.  For instance, a cash register with a graphics
display can show a graphic rendering of the cash drawer, including
coin and bill bins and a number associated with each bin.  A
text-only display on a cash register can list the denominations and
