Aims and objectives
This is a fun demonstration aimed at providing students with an
overview as to how an EPOS (Electronic Point of Sale) system works.
No previous knowledge is required for this activity although students
would benefit from having had ‘real world’ experience
of what happens at a supermarket checkout.
In the classroom
This activity is appropriate for KS3 pupils following the ICT National
Curriculum. It demonstrates an EPOS (Electronic Point of Sale) system
which is used by most shops and supermarkets as a stock control
and to reorder goods. This reduces the time consuming stock control
tasks of manually counting stock and prevents shops from carrying
too much stock.
The pupil is guided through a series of notes explaining EPOS and
then watches an animated demonstration of the EPOS system in action.
This activity could be used as part of Unit 11 of the QCA Scheme
of Work: Data and Misuse. Further discussion can examine the more
accurate, faster and convenient till service given to customers
and the use of information gathered about how well shops are doing
and about the shops' customers through the input at the EPOS terminal.
A homework activity could be to study the information on a supermarket
till receipt identifying the different components and their possible
