What does ARU refer to in electronic transactions?

The term ARU in the context of electronic transactions commonly refers to an Audio Response Unit. An Audio Response Unit is a system that allows users to interact with a computerized system using their voice or touch-tone telephone keypad. This can involve retrieving information, making transactions, or navigating through menus, which is particularly useful in customer service scenarios where users may need assistance or information without the need for live agents.

Audio Response Units are integrated into various electronic transaction systems, enhancing customer interactions by providing automated responses to inquiries and facilitating transactions efficiently. They streamline processes by allowing customers to access real-time information, such as account balances or transaction statements, thereby improving user experience and operational efficiency in environments that handle a high volume of transactions.
