Point of Sale
Point of Sale (POS) is a system used by businesses to process customer transactions, typically involving hardware like cash registers, barcode scanners, and card readers, along with software for managing sales, inventory, and payments. It serves as the central hub for retail, hospitality, and service industries to handle purchases, track stock, and generate reports. Modern POS systems often integrate with e-commerce, accounting software, and customer relationship management tools to streamline operations.
Developers should learn POS systems when building or customizing solutions for retail, restaurants, or any business that handles in-person sales, as they are essential for automating transactions and managing business data. Use cases include developing mobile POS apps for on-the-go services, integrating payment gateways for secure processing, or creating inventory management features to reduce manual tracking. It's particularly valuable for roles in fintech, retail tech, or software consulting focused on business operations.
