The three components of POS in Quick Service Restaurant (QSR) are:

​Point of Sale (POS) Software – The software component is the backbone of any modern point-of-sale system. It tracks all transactions and provides instant reports on what’s going on with your business at any given time. ​

Touch Screen Monitor – A touch screen monitor allows customers to make purchases by simply touching the screen with their finger or stylus (depending on which type of monitor you choose).

Cash Register – The cash register is one of the most important tools in any QSR. It’s how you collect money from customers and payout to employees. Good QSR POS systems have multiple ways to process payments including cash, debit cards, credit cards, and check payments.
