What should cashiers do to prevent counterfeit bills?

Familiarizing themselves with the security features of currency is crucial for cashiers to effectively prevent counterfeit bills. By understanding the specific elements that denote authenticity, such as watermarks, security threads, and color-shifting ink, cashiers can quickly identify discrepancies between real and counterfeit notes. This knowledge allows them to make informed decisions when checking the validity of the bills presented to them.

Merely using a blacklight scanner when deemed necessary may not be reliable since it requires the cashier to be both selective and informed about when to use it. Asking customers if their bills are valid relies too heavily on the integrity of the customer and does not provide a solid verification method. Handling cash without thorough examination negates the crucial step of actively checking for authenticity, thereby posing a risk of accepting counterfeit currency.
