The Safescan 2210s back-loading hopper can hold up to 300 banknotes and accurately count them, up to 1.000 notes per minute. Todays currencies are printed with sophisticated security features that make it hard for counterfeiters to succeed. The 2210 automatically checks every banknote for two distinct security traits: UV markings and bill size. It will pause and beep to alert you when it encounters a suspicious bill; simply remove the offender and press start to resume counting.
