What role does an Electronic Terminal serve in transactions?

An Electronic Terminal plays a critical role in facilitating financial transactions by acting as a point of connection to card networks and financial institutions. It is designed specifically for the purpose of reading card information, processing payments, and communicating transaction details with payment processors and card companies. By enabling the secure transmission of card data, the terminal ensures that transactions are authorized and processed quickly, making it an essential tool in electronic payments.

The other options pertain to functions that do not align with the primary purpose of an Electronic Terminal. For example, machines that process invoices relate to accounting and finance management rather than real-time payment processing. Devices for making phone calls do not serve any financial transaction function and are outside the realm of payment systems. Lastly, a system for managing supply chain logistics focuses on the flow of goods and services, which is unrelated to the transaction processing that an Electronic Terminal specializes in.
