What is one of the primary functions of a POS terminal?

Documenting customer transactions is one of the primary functions of a point-of-sale (POS) terminal. This system records each sale made during a transaction, capturing essential details such as the items purchased, their prices, any applicable discounts, payment method, and customer information if needed. This documentation is crucial for inventory management, sales tracking, financial reporting, and customer service. By maintaining accurate transaction records, businesses can analyze sales trends, monitor performance, and address any discrepancies or issues that may arise.

While options related to generating employee schedules, providing training materials, and facilitating online sales are valuable functions within a business, they are not intrinsic to the core purpose of a POS terminal. The primary focus of a POS system is on the transaction process itself, making option B the most relevant and accurate response.
