Point-of-Sale (POS) is the physical or digital location where a transaction takes place between a customer and a business. It is the point in the retail process where payment is made by the customer in exchange for goods or services, such as the cash register, online checkout page, and self-service payment kiosk.
Traditionally, a POS system consists of hardware and software used to process payments, including a physical cash register, barcode scanner, and credit card terminal. With the rise of eCommerce, however, digital POS systems have become increasingly popular, allowing customers to make purchases and pay online from any location.
