National Cash Register was founded in 1884 by John Patterson, who created the first mechanical cash register. Innovative business practices and a successful sales force made NCR cash registers standard equipment in stores across the country. The Ohio-based company was seen as a high-tech company. NCR assisted in breaking the German Enigma code during World War II. While cash registers remained NCR's main business for several decades, it became interested in computers in the 1950s. The company moved on to produce other products to assist businesses, including transistorised computers, barcode scanners and automated teller machines. (References, 1)

    Unlock the Number 4 lock. This lock is located at the front of the cash drawer. The key labelled Number 4 will open this lock. While locked, the register may not be used.

  2. 2

    Press the amount keys in the left hand bank of keys to enter the amount of the item to ring up the merchandise.

  3. 3

    Press the key that corresponds with the type of transaction being rang up. For example, press "cash" for an item that will be paid in cash or press "charge" for a transaction that is being paid with credit.

  4. 4

    Press the initial key that has been assigned to you as a sales associate. Each employee using the register should have a key assigned to them to be able to track errors or questionable transactions that arise later.

    Press the large operating button on the right side of the machine to operate the register and complete the sale.

  6. 6

    Use the "No Sale" button if you want to open the register without ringing a sale, such as to make change for a customer.

Tips and warnings

  • Do not attempt to stop the drawer from fully opening. It must open all the way before it can be closed. The drawer must be closed before another transaction can be entered.
