What must each cashier have to ensure cash drawer security?

Having locked cash drawers is essential for ensuring cash drawer security because it provides a physical barrier against unauthorized access. When cash drawers are locked, only designated personnel, typically those responsible for handling the cash, can access the funds. This minimizes the risk of theft, both from external sources and from individuals within the organization, as it prevents anyone who is not authorized from easily accessing the cash.

While regular audits are important for maintaining overall financial integrity and can help identify discrepancies, they do not actively prevent theft or unauthorized access in real-time. Security cameras can be a useful tool for monitoring activities and may serve as a deterrent against theft, but they do not physically secure the cash itself. Cash reserves are necessary to ensure that a business can meet its cash flow requirements, but they don't directly contribute to safeguarding the cash drawer.

Thus, locking the cash drawers stands out as the most effective measure specifically aimed at securing cash within the drawer itself.
