Bill counter equipped with counterfeit detection combines counting convenience with additional cash-security features. Depending on the technology used, detection may involve ultraviolet, magnetic, infrared, dimensional, or other verification methods. When a suspicious note is detected, the machine may alert the operator and stop counting. Alongside security functions, many models provide automatic counting, batching, accumulation, and digital display features. This makes them useful for retailers, banks, hotels, wholesalers, restaurants, and cash-handling offices. The machine helps reduce dependence on manual inspection while supporting faster and more organized processing of banknotes.
