What is the abbreviation for a system that processes customer transactions electronically?

A Point of Sale (POS) system is specifically designed to process customer transactions electronically, making it an essential component in retail and food service environments. This system typically includes hardware (like cash registers, tablets, or touchscreen interfaces) and software that help streamline the sale process, track sales, manage inventory, and gather customer data.

In comparison, a Customer Relationship Management (CRM) system focuses on managing a company's interactions and relationships with customers, but it does not focus on transaction processing. An Enterprise Resource Planning (ERP) system integrates core business processes across various departments, including finance, human resources, and logistics, rather than focusing solely on sales transactions. A Content Management System (CMS) is used for managing digital content, which is unrelated to transaction processing. Therefore, the POS system is the correct term for an electronic transaction processing system.
