Automatic Stock Control System in a Supermarket

-  Bar codes are associated to all goods/items sold by the supermarket as a means of identification

-  Every bar code is associated with a stock file on a computer database

-  Customer takes their basket/trolley to POS terminal

-  Bar code on product is scanned at the point of sale (POS) terminal

-  If bar code can't be read, the POS operator has to key in the bar code number manually using a keypad/keyboard

-  Bar code is searched for on the database

-  Once bar code is identified/found, appropriate file/record is accessed

-  Price of good/item is found and sent back to POS

-  Stock level of item is reduced by 1

-  If stock level is less than or equal to the re-order/minimum stock level then the system automatically re-orders goods/items from the suppliers

- This procedure is repeated until all the items in the customer's basket/trolley have been scanned

- When all items/goods have been scanned, customer is given an itemised bill showing a list (with prices) of everything they have bought

- Computer also updates the files comprising daily takings

- If the customer has a loyalty card, the system automatically updates their point's total

- When new goods arrive, bar codes are used to update stock files

- Some newer supermarkets now allow consumers to scan their own trolley/basket and pay for the goods/items using credit card or cash (essentially stock control system is the same for both methods)
