Bar code Scanner:  Bar code scanner is used to scan the bar code on the product to quickly identify the item. So bar code scanner's job to provide input data to the POS system which are used for different purposes which I will explain at the end when we show how we integrate all these components. Many types of scanners are available but the omni-directional Laser bar code scanners are the most efficient and popular. These are available with various kind of interfaces like USB, RS-232, Ethernet etc. and all are equally effective.

Receipt Printer:  Receipt printers are obviously used to generate customer receipts automatically once the sales process is completed. In addition to generating receipts, these are also used to generate "Cash up" reports at the end of the shift /day. Although, thermal receipt printers are the most popular ones, dot matrix receipt printers are also available. Thermal receipt printers are popular because of their amazing printing speed. These printers are available with various interfaces like USB, RS-232, Ethernet etc.

Windows based computer with Touch Screen: Any standard computer will do but an inbuilt touch screen based computer is preferred in POS industry as it is more user friendly and fast. Although, Mac and Android based point of sale software are also available, Windows based software are the most popular ones.

Eftpos Machine: Eftpos machines are used to do debit or credit card transactions. Once the sale is made on POS system and eftpos method is chosen to complete the transactions, amount of the sales transaction is automatically communicated to eftpos machine and the customer swipes his card to pay. Once the card is accepted or declined, the message is poped up on the POS screen.

As shown above, Receipt printer, bar code scanner and eftpos machine are connected to the Windows based computer with inbuilt touch screen via their respective interfaces. In this example, printer and the scanner is connected using USB interface. Printer kicks the cash drawer and the computer and the eftpos machine are on LAN connected with the internet.

KISS POS (Or any other point of sale software) is installed on this computer and your point of sale system is ready to be used.

The basic process goes like this. When the customer comes with an item to buy, you scan the item on bar code scanner, KISS POS, picks up the item and its price from the database, shows it on the screen. You may change the quantity if there are more than one items, and then complete the sales transaction either by touching "cash" button or "eftpos" button as the case may be. For example, if the item costs $5 and the the customer gives you $20, you touch button marked $20, system will show you to return $15 to customer and the cash drawer will get kicked out. You place $20 in the cash drawer and return $15 to the customer and close the cash drawer. Similarly, if the customer decides to pay by debit card, you touch "eftpos" button and the software will automatically transmit the amount to the eftpos unit, and the customer will swipe the card, enter pin etc. on the machine and once the card is accepted, the result will be shown on your POS screen.

These are the very basics of any point of sale system. However, if you want to go into detail, you may like to watch the following video that we made to explain various features of KISS POS in detail.
