Money Counting Machine

Overview

A money-counting machine tallies a stack of banknotes quickly and accurately, and on better models also checks each note for authenticity and reads its denomination. Notes are fed from a hopper, separated one at a time, flung past a bank of sensors, and stacked in an output pocket while a counter ticks up. By replacing hand counting it removes both the labour and the miscounts of cash handling in banks, retail, and casinos.

The machine is a compact desktop unit with an angled input on top and a catch pocket on the front. The Housing holds the body, hopper, and stacker shells. The Feed System separates and launches notes, the Note Transport guides them through the sensor zone, and the Detection Array block carries the counterfeit and counting sensors. Counted notes land via the Stacker, with results shown on the operator Operator Display and a Customer Display facing the payer, all fed by the Power Supply.

How it works

A stack is dropped into the hopper and the Feed System roller, working against a friction pad, peels off the bottom note and accelerates it into the path. The Note Transport rollers carry it at constant speed through the Detection Array zone in a few milliseconds.

There, a contact image sensor reads each note's pattern while ultraviolet, magnetic, and infrared sensors check the security features: UV-fluorescent fibres, magnetic ink, and IR-transparent zones that genuine notes carry and most fakes lack. The Main Control Board compares these signals against stored templates to verify the note, identify its denomination, and increment the count. A double-note or chained-note error halts the run. Verified notes are thrown by the Stacker wheel into the front pocket in a neat fan. The running total and any suspect-note flag appear on the Operator Display, while the Customer Display shows the customer the same figure.
