Name one tool used to assist with transaction accuracy.

A cash register is primarily designed to record sales transactions, manage cash inflows and outflows, and help ensure that the financial data from those transactions is accurately recorded. In a banking environment, cash registers can serve as a reliable tool to assist tellers in managing transactions efficiently and reducing errors. They typically provide functions such as tallying totals, applying taxes, and handling various forms of payment, which all contribute to maintaining transaction accuracy.

In contrast, a calculator might be used for simple arithmetic but doesn't necessarily provide the integrated features that a cash register offers for transaction management. A document management system focuses on organizing and storing documents rather than handling the complexities of cash transactions. A financial advisory tool is primarily aimed at providing investment guidance and advice rather than assisting in routine transaction processing. Therefore, a cash register stands out as a vital tool specifically tailored to enhance transaction accuracy in a banking context.
