What is a technology that will allow a customer to check their account balance through automated prompts?

The technology that allows a customer to check their account balance through automated prompts is Interactive Voice Response (IVR). IVR systems are designed to interact with callers, gather information, and route calls to the appropriate recipients based on the user's voice responses or keypad inputs. Customers can navigate through a series of automated prompts that lead them to the option of checking their account balance, thereby providing efficient and convenient self-service.

This technology significantly enhances customer experience by allowing them to access information quickly without the need to speak directly to a customer service representative. IVR systems can streamline operations and reduce wait times, which is particularly beneficial for high-volume scenarios like checking account information.

While the other options listed may relate to aspects of telecommunications or operational processes, they do not specifically provide the means for customers to interact automatically or retrieve account information efficiently like an IVR system does.
