Resources

Sheet Title Notes Format
1 ICT in the Supermarket You will be given a copy of this to fill in during lesson 1
2 Language of ICT You will be given this sheet as homework at the end of the unit  

 

Introduction

In this unit you will investigate the large-scale use of data by businesses, and particularly in shops. You will  find out about electronic stock control systems, including the use of bar codes and electronic point of sale (EPOS) systems, and loyalty cards. We will look at the social implications of loyalty cards and EPOS systems.

We will also explore the ways in which other organizations collect data, the Data Protection Act, and the different ways data can be protected from misuse or damage.

This unit involves extensive class discussion and we will use the internet to find information.

This unit is expected to take approximately 3 lessons.


 

Lesson 1

Think about a trip to the supermarket. How is ICT used?

You will be asked to write down ideas in groups on this sheet, then feed back to the rest of the class.

Focusing on one or two things will we discuss the benefits and drawbacks to customers and businesses.

 

Loyalty cards

What are the benefits of loyalty cards to the customer?

What information is collected by the supermarket? (look an application form)

How will they store the data?

What links this information to the card?

What are the benefits of loyalty cards to the supermarket?

 

Next we will think about the goods on the shelves.

Are the goods priced?

Where is the price?

How does the supermarket know the price at the checkout?

What are the three pieces of information stored in a bar code?

 


 

Lesson 2

The bar codes below were all found in my house. Copy down the numbers below the bar code then go to this website. Here you will be able to find the company that made the items and the company in which they were made.  The website will not tell you the product details - you would have to pay to get this information. Can you guess what the products are?

On the website, type the barcode number in the box below the words:

Number Search
EAN/UCC-13

 

A similar system is used with books. They each have an ISBN (International Standard Book Number). Use the Internet bookshop Amazon to find which books have these ISBN numbers. Type the numbers into the Search Our Shops box.

0747542155   0192833669   0590660543

Homework is to find out which loyalty card systems family members belong to and what reasons they have for using them.

Lesson 3

This lesson you will find out what EPOS and EFTPOS stand for.

On a piece of plain paper draw a common EFTPOS system used in a large supermarket. Label each part of your drawing. Put the title:

An Electronic Funds Transfer Point Of Sale System

Below are some pictures of parts of an EFTPOS system.

 

Make sure you include, and label, the following:

barcode scanner electronic weighing scales
keyboard (could be a touch screen) card swiper
display screen cheque printer
cash drawer receipt printer


Next, write a paragraph explaining what happens when you buy a bottle of HP Sauce from a supermarket describing exactly which bits of data are used at each stage. Include the bar code and the loyalty card in your description.

How does the information gathered by the supermarket help with

  • stock control

  • making decisions that will improve the shop's profits

List other ways in which a persons personal and shopping information can be used by the supermarket.
