Top-Loading Bill Counter counts 200 bills per minute and features ultraviolet sensors that check for suspect bills. It stops counting and warns you with a clear alert message if a suspect bill is detected. Infrared detectors ensure money bills are counted accurately and avoid errors such as chains, double bills and half notes. Seven operation modes save time: ValuCount, Automatic, Manual, Count, Add, Batch and Add plus Batch for various money-counting needs. ValuCount uses the selected single denomination to calculate the total monetary value of bills counted. It does not automatically recognize the value of the bill.
