The Billcon N-131 Bill Counter has two magnetic detection sensors to double your protection against counterfeit notes. An instant audible tone works as an alarm to notify the user of suspicious or fake notes. A flashing light appears on the electronic display and to identify more than ten types of possible detection problems. The three-digit LED on the Billcon money counter has large red, easy-to-read symbol displays showing the current bill count. Features include variable speed settings that range from 50 to 1,000 banknotes per minute and pre-programmed controls. The controls are programmed to automatically recount a preset batch number of notes (repeat mode), to automatically stop counting when reaching a preset batch number (batch mode), to automatically count the batch of notes and record the running total (add mode--accumulate function), and a default counting function (count mode).
