NCR Stamping Phone Distributed throughout the store in the various departments, stamping phones are used in the selling departments by the clerks or wrappers in getting a printed authorization on the sales-slip and a perforated authorization in the address labels. The phones should be placed near the wrapping desks so that the clerks can conveniently reach and answer the phones while wrapping the purchased aricles. The stamping phones are equipped with a one-line printing device and a perforating die. Phones were configured with from 1 to 10 intercom pushbuttons to ring the appropriate credit specialist in the back room. Each button was coded for the range of customer last names handled by each credit authorizer. Pushing the button buzzed the authorizer, who looked up the customer's credit limit on paper files and, if appropriate, authorized the credit sale. |

When the authorizer pushed a button, the sales
slip was stamped and perforated, providing an
unchangeable record of the authorization on both
original and duplicate copies of the sales slip. The original was usually filed in the bottom drawer and collected periodically for posting to the customer's account, while the copy was given to the customer. |

NCR Type C Authorizer's Master Phone Stores with small credit departments had this simple phone at each credit verification station in the back room. Buttons were configured to connect to the major departments on the sales floor, as needed. Phones were configured with from 1 to 10 intercom pushbuttons. The authorizer answered a call by selecting the department button next to a lit lamp. The voice link was used to get the customer name and transaction amount. When a sales slip was properly inserted in the sales clerk's phone, the red light would glow. If the account was in good standing, the authorizer pressed the "Stamping" button to activate the stamping unit in the sales department. A buzzing button was provided to turn on or off an audible sound when a lamp was lit. A ringing button permitted the authorizer to signal the sales clerk. |

NCR Credit Authorizer Switchboard Large stores with many authorizers and departments typically needed more complex equipment. This switchboard unit was placed between two authorizer stations, so it was near the cycle billing files for the group of accounts it was intended to serve. Calls were answered by inserting a connecting plug in the hole beside the lit lamp. |
