| Shopping Systems | |||
|
Many large shops and supermarkets now operate computer-based
systems. These allow simple data entry
systems, on-line payment and automatic stock
control.
|
|||
| Goods may be labelled with bar
codes that are passed over a bar code
reader at the check out. The bar code is read and transmitted
to a central computer that searches its database and returns the price and
description of the item to the EPOS terminal. Data may also be input using
a keypad.
The price and description of the item may be output on a small LED screen.
|
EPOS=Electronic Point Of Sale. | ||
|
Payment for goods may be made by :
EFT = Electronic Funds Transfer EFT allows customers to pay for goods using credit or debit cards. The amount of money is automatically transferred from the customer's bank account to the shop's bank account.

| The shop may set its own pricing, such as for sales or special offers, by adjusting the price of the items on the computer database. | |||
