How a POS Works
Point of sale systems for small business In Nairobi Kenya
The chief job of the POS is to calculate the total cost of an order, take payment, and log the transaction.
The process starts by recording the items to be purchased. In a supermarket, for example, this would involve entering the items into the POS with a barcode scanner. The software will record all the data, including the name and quantity of the items being purchased.
