A POS system is mainly dependent on the core function of its software. Every feature of your system will be decided by the software you choose. They can be consistent with software only or a combination of both hardware and software.

From there, the cashier records the item i.e. scans the barcode with a scanner to add the details. If you are digital paying, it will require it to be typed in it.  
  2. Once all the items are added and typed into the system, the cashier starts to sum up the total. He may ask you how you are going to pay for the item. If you are paying in cash, he would simply take the payment. If you are paying through a credit card, then it would require you to swipe or tap the card to a card reader. 
  3. The card reader is integrated with the POS system and collects the data perfectly. If the system is not integrated then your cashier must manually put the cash details in the system. 
  4. After successfully entering the payments, you will receive a receipt of all the transaction details. The cashier might offer you referrals or loyalty points.
