How Souvenir Coin Machines Actually Work

A souvenir coin machine is simpler than it looks: pre-struck medals in a hopper, a payment module, a dispensing path and a mobile connection that reports what happened.

There is no press inside the cabinet. The medals are struck in our factory, loaded into the machine as finished pieces and released on payment. That is why the unit needs a power socket and nothing else, makes almost no noise, and requires no operator training beyond how to open it. This page sets out the purchase flow, what sits inside the cabinet, what your venue has to provide, and how long an installation takes from the first conversation to opening day.

What Happens When a Visitor Buys a Coin

Six seconds, described in six steps.

01

The Visitor Chooses a Design

Available designs are shown on the front of the cabinet. Where a venue runs several, the visitor selects one with a button or a touch selection.

02

Payment

Contactless card, mobile wallet, coins or notes, depending on how the machine was configured for that market. The transaction itself takes a few seconds.

03

Authorisation

A card or wallet payment is authorised over the machine’s own mobile connection. A cash payment needs no connection at all, which matters at sites with poor coverage.

04

Dispensing

The selected medal is released from its hopper into the collection tray. Nothing is pressed, cut or heated inside the cabinet.

05

The Counter Updates

The sale is recorded against that specific design with a time and date, and the remaining stock level is recalculated.

06

The Dashboard Reports

Sales and stock appear in your dashboard within minutes. A low-stock threshold triggers a restocking alert before the machine can run empty.

What Is Inside the Cabinet

Four components, all replaceable independently.

Medal Hoppers

Separate hoppers per design, loaded with finished struck medals. Capacity depends on the cabinet line and is quoted in medals rather than in volume, because that is the number that decides your restocking round.

Payment Module

Chosen per market: contactless reader, coin and note acceptor, or both on the same unit. Modules can be swapped without touching the rest of the machine if an acquirer or a currency changes.

Control Board and Modem

Runs the selection logic and reports over mobile data. It keeps a local record of every transaction, so a dropped connection delays reporting rather than losing sales.

Cash Box and Locks

Present only on machines configured to take cash. On a cashless unit there is no cash box at all, which removes the main reason anyone would attack an unattended machine.

What the Venue Provides

Five things, none of them unusual.

A Standard Power Socket

An ordinary mains socket within reach of the placement. No dedicated circuit, no three-phase supply, no plumbing and no network cable.

Floor Space From 0.25 m²

The smallest cabinet needs roughly a quarter of a square metre. The largest needs about a square metre, plus clearance to open the door for restocking.

Usable Mobile Coverage

The modem needs a workable mobile signal. In a basement, a thick-walled heritage building or a steel-framed terminal we test this before installation rather than discovering it afterwards.

One Named Contact

A single person on site who can open the machine and who receives the restocking alerts. No technical background required; the briefing takes about ten minutes.

A Window for Restocking

A time when somebody can reach the machine to refill it. For most venues that is before opening or after closing, once every few weeks.

Choosing a Cabinet for Your Placement

The cabinet follows the space and the traffic, not the other way round.

Small Coinmat

From 0.25 m²

For a ticket hall, a vestibule or a corridor where floor space is the constraint. The easiest install to get approved and the quickest to relocate if the first position turns out to be wrong.

Midi Coinmat souvenir coin vending machine

Midi Coinmat

Mid capacity

For a position you can reach weekly. Mid-capacity loading means fewer interruptions to your own staff routine.

Mini Lux souvenir coin vending machine

Mini Lux

Premium finish

For a placement that is on show: an entrance hall, a premium lobby, a signature building where equipment has to look deliberate rather than tolerated.

Big Coinmat souvenir coin vending machine

Big Coinmat

High volume

For a single main entrance moving thousands of visitors a day, where the machine cannot be opened during opening hours.

Indoor and Outdoor Builds

Indoor units are specified for heated and air-conditioned interiors. Outdoor units add a sealed enclosure, protective roof, weather seals and corrosion-resistant hardware, with heating or additional dust protection added for the specific climate. If a sheltered indoor position exists, we will recommend it first: it costs less to run and the machine lasts longer.

From Order to Opening Day

Six phases. The one you control is the second.

Site Review

We look at footfall, placement options, payment methods and mobile coverage. Usually a conversation and a few photographs rather than a site visit.

Coin Design

Artwork is prepared and revised with you. The production clock does not start until you approve it, which makes this the stage that sets the overall timeline.

Die and Sample Strike

The die is cut and a sample strike goes to you for inspection before the full run begins.

Production

Cabinet built, wrap printed and applied, medals struck and counted. The duration depends on configuration and is quoted as a firm date rather than a range.

Freight

Sea freight for scheduled rollouts, air freight when a season deadline is at stake, with documentation prepared for the destination market.

Installation Day

Positioning, power-up, connection test, loading, a short staff briefing and a first test purchase. Typically a couple of hours for a single unit.

Three Ways to Put One In

The process above is identical in all three; only the invoice differs.

Machine Purchase

You buy the unit and keep the full margin on every medal sold.

Revenue Share

We supply, install and service the machine; you provide the location and we split the revenue on agreed terms. No capital outlay.

Service Package

Restocking, design refreshes, preventive maintenance and reporting for venues that already own a machine.

Frequently Asked Questions

No. The medals are struck in our factory and loaded as finished pieces. Some competing formats flatten a circulating coin under a hand-turned press; ours does not, which is why it needs no supervision and raises no questions about currency handling.

A mains socket and a usable mobile signal. No plumbing, no network cable, no dedicated circuit and no compressed air.

Cash purchases continue as normal and the machine keeps a local record of every sale. Card payments need a live connection; when it returns, the stored data syncs to the dashboard and nothing is lost.

Your own staff, in a few minutes, with a key. Where a venue prefers not to handle it at all, restocking can be folded into a service package.

You do not have to check. The machine reports stock continuously and sends an alert when a design falls below the threshold you set.

A couple of hours on site for a single unit, including the staff briefing and a test purchase. The long part of the project is the coin design, and that runs to your schedule rather than ours.
