The "Ringing In The Changes" scam involves a "customer" asking to exchange a quantity of money, usually a large sum, for smaller change and then using well-rehearsed scripts and sleight of hand causing confusion to the cashiers, resulting in them handing over more money than the original amount tendered. Therefore, cashiers are asked to be aware of these types of crimes and to be extra vigilant especially during the busy period when they are particularly busy serving a lot of customers. These busy periods provide the fraudsters with the opportunity to use skilled techniques designed to fluster and confuse the cashiers while appearing to be genuine consumers merely asking for notes or coins to be changed.
