• Cashier Window
• Example cashier session step by step

The cashier window contains a series of purchases a cashier would enter into the system. All the tasks can be performed easily by using a mouse and a keyboard.

There are 6 blanks and a summary of purchases in form of a receipt.

The 6 blanks are:

• UPC - 12 digits Universal Product Code
• Quanity - Number of items purchased
• Amount Owing - The total amount of money payable
• Cash Given - The total amount of cash received
• Change - The total amount of cash given back to the customer as change
• Credit Card - The customer's credit card number

Login to Cashier Interface

1. Enter username and password to login onto the system.
2. Click the "Cashier" button on the Main Menu.
3. Cashier now on the Cashier Interface.

How to Enter a Purchase

Note: Since a cashier is associated with only one store, that store's inventory will be affected by the purchases entered by the cashier.

1. Enter UPC number in the UPC field (in which the cursor is already active) and press RETURN.
2. The UPC number entered will appear in the RECEIPT under the UPC column, as well as the item's description. At this point, the Quantity field should be left blank.
3. If an invalid UPC entered, the RECEIPT will show NO change and a dialog box would appear. The dialog box indicate that the UPC entered is not valid. You can click (use the mouse) and click on the UPC number entry box again and re-enter the UPC number.
4. If the UPC is valid, the cursor now should active in the Quantity entry box. Enter the amount of purchases in this field.
5. If you entered 0, the purchase is essentially aborted and its corresponding row in RECEIPT is erased.
6. If a non-zero/positive Quantity number is entered, the price of the item is retrieved from the database, and the price is then multiplied by the quantity entered, and the result is appear on the Amount Owing output box.
7. Then you should enter the amount of cash given on the Cash Given entry box. Thus the amount owing will minus the cash already given and is then shown in the amount owing output box.
8. If the amount of cash given is greater than the amount owing, the difference will be shown on the Change output box.
9. If the customer use Credit Card instead of cash, just enter the Credit Card Number in the
10. Credit Card box.

Is it possible to enter fractions in the Quantity field? (e.g. produce is sold by the kilogram)

Receipt

The receipt is updated with the quantity purchased. There is a scroll bar in the receipt portion of the window, where the cashier may use to scroll through the list of purchases already made during this transaction.

Refunds and Foreign Exchanges

It is assumed (as mentioned previously) that the cash registers will handle refunds and foreign exchanges (ie US$) - the system will receive finalized purchases. Therefore this crude cashier interface is provided to test the system, and/or to make finalized purchases. The UPC and Quantity fields are then reset, with the cursor being made active in the UPC entry box. At any point and time, the cashier may enter the cash given (using the mouse to click inside the Cash Given entry box) and have the Amount Owing and Change output fields updated automatically.

Exit the Cashier Window

To exit (return to the Main Menu and terminate transaction), just click on the Exit button on the bottom right hand corner of the Cashier Window. The inventory of the store that cashier works for will be updated to reflect the purchases made.
