The three components of POS in restaurants 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. It also provides you with detailed information about your customers so that you can better serve them in the future.

​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). These days most retailers use a combination of both touch screen monitors and traditional credit card readers so that they can still accept cash payments if necessary. Some retailers may also choose to have multiple monitors at different checkout stations so that customers don’t have to wait for one person to finish up before being able to pay for their items.

​Cash Register – The cash register is one of the most important tools in any restaurant. It’s how you collect money from customers and payout to employees. If your cash register is down or not working properly, it can cause major problems for your business. Good POS systems have multiple ways to process payments including cash, debit cards, credit cards and check payments.
