ICT in Supermarkets

Supermarkets use computer systems to:



Sell goods to customers and process payments at
checkouts.



Monitor and Control stock by automatically generating
orders for more products if the stock is low.



Perform sales analysis to find out which products sell
well/not so well.



Collect data about customers using loyalty cards
whenever money is spent in store. This data is used to
analyse the spending habits of customers and send them
offers for the type of products they buy regularly.

EPOS

EPOS = Electronic Point Of Sale

Supermarket checkouts are called EPOS
terminals.

EFTPOS = Electronic Funds Transfer (at
the) Point Of Sale

These are checkouts that can handle debit
or credit card transactions/payments.

EPOS



Every EPOS terminal in a supermarket is
connected to a minicomputer in the store, where a
database of product information is stored.



The computer is linked to the supermarket
chain’s mainframe computer using a
telecommunications link such as a telephone line
or satellite dish.

Have a look next time you’re at a supermarket!

EPOS

Can you recognise the input/output
components of an EPOS terminal?

EPOS



Advantages of using EPOS systems:



Shelves are well stocked, fresh food is readily available
and products rarely run out (Stock Control);



Customers are dealt with quickly at the checkout;



Customers receive a fully customised receipt;



Goods can be paid for at the till with a credit or debit
card using EFT;



Accurate and up
-
to
-
date sales analyses are available
for managers;



Customer’s buying patterns can be used to promote
certain goods/products.

EPOS



Disadvantages of using EPOS systems:



EPOS systems are expensive to install;



EPOS systems require regular maintenance;



Technology must be kept up to date if a competitive
edge is to be maintained against rival supermarket’s
systems.

So, that’s EPOS… but how does the
information about the product get
into the system??

Barcodes



UK supermarkets use barcodes to represent a 13
digit number which identifies 3 things:



The name of the product;



It’s country of origin;



The manufacturers details.

Barcodes

What happens when a barcode is scanned at
the EPOS terminal?



Barcode number is sent to the branch computer.



Branch computer uses the number to search the stock
file for the products details (price and description) and
sends it back to EPOS terminal.



Branch computer updates the stock levels to show one
has been sold.



Products details are displayed on EPOS terminal and
printed on receipt.



The price is added to the total cost of groceries so far.

Online Grocery Shopping



Allows customers to order their groceries from
home and have them delivered to their doors.



Main advantage is that there is no need to visit
the store.



Good for people who work unsocial hours.



Good for people who cannot leave the house
physically.

Online Grocery Shopping



Main disadvantages of ordering groceries online:



You can’t examine the goods before buying them.



Out of stock items could be replaced with something
similar that you don’t really want and may have to send
back.
