Control Systems: EPOS
EPOS stands for Electronic Point of Sale. This is a general name for the computerised tills that you see in shops and supermarkets.
EFTPOS stands for Electronic Funds Transfer at Point of Sale. This is where customers can pay for goods using credit or debit cards.

|This is how an EPOS system works:
EPOS systems can be linked to loyalty card databases or analysis software to help shops predict trends in sales and more effectively order items in the future.
- A product's bar code is scanned by a laser scanner on the till.
- The computer system finds the current price in its database.
- The price is sent back to the till which adds it to the current sale.
- The till prints an itemised receipt.
- The computer reduces the recorded stock by one.
- If an item's stock falls below a pre-set "reorder level", an order for more stock is sent to the warehouse or supplier.
