During the late 1980s and 90s, manufacturers developed stand-alone credit card devices to easily and securely add credit card processing to POS systems. These relatively simple devices have evolved continuously to handle multiple applications (credit card processing, gift card activation, age verification, employee time tracking) on one device. Some wireless POS systems for restaurants not only allow for mobile payment processing, they also allow servers to process the entire food order right at tableside.

Most retail POS systems do much more than just "point of sale" tasks. Many POS systems can include fully integrated accounting, inventory management, open to buy forecasting, customer relation management (CRM), service management, rental, and payroll modules. Due to this wide range of functionality, vendors sometimes refer to POS solutions as retail management software or business management software.
