This is how an EPOS system works:
  1. A product's bar code is scanned by a laser scanner on the till.
  2. The computer system finds the current price in its database.
  3. The price is sent back to the till which adds it to the current sale.
  4. The till prints an itemised receipt.
  5. The computer reduces the recorded stock by one.
  6. If an item's stock falls below a pre-set "reorder level", an order for more stock is sent to the warehouse or supplier.
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.
