Count It Up

Short answer: A banknote counter feeds bills one at a time through rollers past sensors that register each note, and many measure size or thickness to catch doubles. Higher-end models check ultraviolet and magnetic features to flag counterfeits and can sort mixed denominations.

Machines like these count hundreds to more than a thousand notes a minute. The footage shows a counter riffling through a stack of bills.

Video transcript: Count It Up: Rollers Pull Each Bill Past Sensors at High Speed

Did you know? Automatic money counters use rollers by feeding bills into the machine, where the rollers guide them through a series of sensors. These sensors detect the bill's size, thickness, and sometimes even its authenticity. The rollers quickly pull each bill through at high speeds, allowing the machine to tally the number of bills accurately. Some advanced models also scan for counterfeit bills using UV or magnetic sensors. The machine's precision and speed make it ideal for businesses handling large amounts of cash, significantly speeding up the counting process. NOW YOU KNOW!
