Abstract

Fraud from photocopied receipts is a significant source of loss for merchants. Many merchants print the receipt with colored ink and some use preprinted paper (like a water mark). The availability of color copiers and color Personal Computer (PC) printers reduces the effectiveness of using color printing. It is also fairly easy to secure preprinted paper stock from the stores supply, especially when the culprit may be an employee. This disclosure describes a method of printing cash receipts that has no visual evidence that a fraud protection system is in place.

Fraud Preventing Cash Receipt Using Magnetic Ink

      Fraud from photocopied receipts is a significant source of loss
for merchants.  Many merchants print the receipt with colored ink and
some use preprinted paper (like a water mark).  The availability of
color copiers and color Personal Computer (PC) printers reduces the
effectiveness of using color printing.  It is also fairly easy to
secure preprinted paper stock from the stores supply, especially when
the culprit may be an employee.  This disclosure describes a method
of printing cash receipts that has no visual evidence that a fraud
protection system is in place.

      This disclosure consists of printing the sales receipts with
magnetic ink of the type used in printing Magnetic Ink Character
Recognition (MICR) characters on checks.  Ink jet printer
manufacturers are currently developing magnetic ink for ink jet
printers.  When available, it will be practical to print sales
receipts using magnetic  ink.  There is already one ink jet sales
receipt printer on the market.

      A MICR sales receipt would look like a normal receipt.  When a
refund is requested, the receipt is passed through a MICR character
reader which would have a mode that signals the operator that the
receipt has been printed with magnetic ink.  The store can then be
assured that the receipt was printed on one of their printers and is
probably valid.  The presence of MICR readers at the check stand
makes this a practical means...
