What is a POS system?

Point-of-sale (POS) systems are used to handle the customer checkout process in stores, restaurants, and in any other business conducting in-person sales. Most POS systems are located at the checkout counter, but an increasing number of small businesses use mobile POS systems to process payments from a tablet or smartphone.
