Currency Exchange Kiosk Product

Overview

A currency exchange kiosk automates the bureau de change: it buys foreign banknotes at a quoted rate and pays out local currency, or the reverse, with no teller present. Mechanically it combines two machines that also exist separately — a bill-payment-grade note recycler on the intake side and an ATM-class dispenser on the payout side — and adds the regulatory layer that makes unattended money changing legal: an ID Verification System that reads passports, and a Surveillance System package that ties a face to every deal. All cash paths terminate inside an EN 1143-1 graded Cash Safe.

Operators deploy these machines in airports, border crossings, hotels, and shopping centres, where staffed counters cannot justify 24-hour wages. A typical unit handles 10–20 currencies on the buy side and pays out two to four, with the rate table refreshed every minute from the operator's wholesale feed through the Comms Router.

How a transaction works

The customer selects the currency pair on the touchscreen and feeds notes into the Bunch Feeder, up to 30 at a time. Each note passes the Recognition Unit, which images both faces with contact image sensors under visible, infrared, and ultraviolet light while Hall Sensor arrays read the magnetic security thread and magnetic inks. The unit matches the result against stored templates to determine currency, denomination, series, and fitness. Notes that fail authentication return through the Reject Tray; the rest wind onto the Escrow Drum.

Escrow is the legally important step. The kiosk quotes a binding amount only after counting the physical notes; the customer sees the total, the rate, and the commission, and can still cancel. On cancellation the escrow drum unwinds and returns every note. On confirmation the notes commit: common denominations spool onto the Recycling Drum set for reuse in later payouts, and the remainder drop to storage inside the safe. Recycling matters economically — each drum holds 60–100 notes of one high-turnover denomination, and reusing customer cash for payout can halve the cash-in-transit visits the machine needs.

Payout runs through the Payout Dispenser. Each Dispense Cassette holds about 2,000 notes of one denomination behind its own lock; the Pick Module separates one note per pick with a friction roller working against a counter-rotating retard wheel, at up to eight notes per second. Every note flies past the Double Detect, a thickness gauge that diverts doubles, skews, and taped notes into the locked Reject Bin for later reconciliation. The verified bundle stacks behind the Presenter Slot, the shutter opens, and if the customer walks away the cash retracts after about 30 seconds and the deal reverses. The Receipt Printer cuts a receipt carrying the rate, commission, and a serial deal reference.

Identity and compliance

Anti-money-laundering rules cap anonymous exchange — under EU AMLD5 most operators set the threshold between €150 and €1,000 per rolling period. Above it, the kiosk demands a document. The Document Scanner images the data page at 400 dpi, decodes the ICAO 9303 machine-readable zone, and checks security print under the switched white, UV, and infrared banks of the ID Illuminator. For ePassports the ePassport Chip Reader performs BAC or PACE access and pulls the signed data groups from the chip, defeating photo substitution. The Face Camera then runs a 1:1 match between the live customer and the document portrait.

Every deal is journaled by the Core PC with the ID record, the Scene Camera snapshot, and serial numbers where the recognition unit captured them, and the DVR Module keeps 30–90 days of indexed footage. This record set is what licensing authorities audit.

Security engineering

Cash sits behind layered protection. The Safe Body is composite-filled steel graded CEN II–III; the Safe Door carries glass-plate relockers that fire if the Safe Lock — an EN 1300 class B electronic lock with one-time replenishment codes — is punched or torched. A Seismic Sensor alarms on drilling or grinding, and the Anchor Kit bolts the 400–700 kg machine through the slab against ram-raid removal. The electronics live in the upper Cabinet Body behind a Service Door on a separate key plan, so technicians service paper and boards without ever seeing cash; Alarm Switch contacts report every door event to the monitoring centre.

Power and availability

The machine draws about 300 W from a 230 V feed. An online UPS rides through short outages so an in-flight deal either completes or refunds from escrow — a half-finished exchange is both a customer-service and a reconciliation problem. The fanless Core PC runs a hardened OS, and if the rate feed drops, the kiosk widens its spread or suspends trading rather than deal on stale prices.
