How Much Does It Cost to Convert a Laundromat to Card?
The cost to convert a laundromat to card is priced per machine plus a per-store layer, and the published ranges are unreliable because they average very different products. What decides your number is compatibility: what your specific models and control boards support. Get quotes against your equipment schedule.
Key takeaways
- Compatibility drives the price, more than store size does.
- Some machines cannot be converted at all, which turns a payment decision into an equipment decision.
- The cheapest time is during a retool, when the constraint disappears and labor is already committed.
- Ongoing fees belong in the comparison, because they recur where the hardware does not.
What Are You Actually Buying?
| Layer | What it covers | Scales with |
|---|---|---|
| Per-machine hardware | Readers or retrofit kits, plus any adapters | Machine count and compatibility |
| Kiosk / value-transfer unit | Where customers load value | Per store, mostly fixed |
| Network and installation | Wiring, connectivity, commissioning | Store size and layout |
| Platform / software fees | Ongoing, sometimes charged per machine | Recurring |
| Processing fees | Percentage and per-transaction | Recurring, with volume |
The first row is the largest and the most variable, because it depends on what your machines are. A basic tap-to-pay retrofit and a full system with screens, tiered pricing, remote management and loyalty are different products at different prices, and averaging them produces a range wide enough to be useless.
Why Is Compatibility the First Question?
Because it determines both the cost and whether the project is possible.
Ask the vendor to price against your equipment schedule — make, model, serial and control generation for every machine — before any other conversation. The answers fall into three groups:
Fully supported. Straightforward retrofit, full feature set, lowest per-machine cost.
Supported with adapters. Higher per-machine cost, and sometimes reduced functionality.
Not supported. The machine has to be replaced to be converted.
That third group is where budgets break. If a meaningful share of your fleet cannot be converted, you are choosing between a partial conversion — two payment systems in one store, which confuses customers and complicates reporting — and bringing forward a retool nobody planned. See converting from coin to card.
When Is It Cheapest?
During a retool. New machines arrive card-ready or card-compatible, the installation labor is already being spent, the store is already disrupted, and the compatibility constraint disappears entirely. The incremental cost of adding the payment system at that point is far below doing it as a standalone project — see retool cost.
When the coin infrastructure needs investment anyway. If the changer is failing, the comparison is not conversion versus nothing; it is conversion versus replacing coin equipment you may not want long term.
Not mid-life on a fleet you will replace soon. Converting machines with three years left means paying for the same capability twice.
What Are the Ongoing Costs?
The hardware is a one-time cost. These are not:
- Processing fees, a percentage plus a per-transaction charge. In a small-ticket business the fixed per-transaction component matters more than the percentage — which is the whole reason reload models exist. See card processing fees.
- Platform or software fees, sometimes charged per store and sometimes per machine.
- Gateway or kiosk fees.
- Support and replacement for readers that fail.
Model these per dollar of revenue rather than per transaction, and compare that against what coin handling currently costs you in collection time, counting, and coin-box losses.
What Do You Get Beyond Payments?
Two things worth weighing against the cost.
Pricing flexibility. Coin pricing is constrained to quarter increments and requires physical adjustment. Card pricing can be set precisely, varied by machine size and changed centrally, which makes disciplined pricing practical rather than theoretical.
Machine-level data. Starts, cycle revenue, price history, refunds and management functions, all exportable. That is an operating tool now and a diligence document later — verifying revenue in a coin store is the hardest part of laundromat diligence, and a store that can export cycle data removes most of that friction. See how to verify laundromat income.
The second benefit only accrues over time. A system installed two months before listing produces two months of history, which is not what a lender's valuation is built from.
Why Does Compatibility Decide the Budget?
Because it determines both the cost and whether the project is possible, and it is answered per machine rather than per store.
Ask the vendor to price against your actual equipment schedule — make, model, serial and control generation for every machine — before any other conversation. The answers fall into three groups. Fully supported, meaning a straightforward retrofit at the lowest per-machine cost. Supported with adapters, at a higher cost and sometimes reduced functionality. And not supported, where the machine has to be replaced to be converted.
That third group is where budgets break. If a meaningful share of the fleet cannot be converted, you are choosing between a partial conversion — two payment systems in one store, which confuses customers and complicates reporting — and bringing forward a retool nobody planned.
When Is the Cheapest Time?
During a retool, by a wide margin. New machines arrive card-ready, the installation labour is already being spent, the store is already disrupted, and the compatibility constraint disappears entirely.
The second-best moment is when the coin infrastructure needs investment anyway. If the changer is failing, the comparison is not conversion against nothing — it is conversion against replacing coin equipment you may not want in five years.
The worst moment is mid-life on a fleet you will replace soon, because converting machines with three years left means buying the same capability twice.
A fourth consideration applies if a sale is in view: the verification benefit accrues to the data history, not to the hardware. A system installed two months before listing produces two months of history, which is not what a valuation is built from.
Summary
No published figure will match your store, because compatibility drives the cost and your machines are specific. Price it against your own equipment schedule, find out early which machines cannot be converted, and put the recurring fees in the comparison alongside the hardware. If a retool is anywhere in the next few years, waiting and doing both together is almost always cheaper than doing them separately.

Frequently Asked Questions
What does a coin-to-card conversion cost?
It is priced per machine plus a per-store layer for kiosks and platform, and no published figure is reliable because the range spans a simple tap reader and a full system with screens, tiered pricing and loyalty. Get quotes against your actual equipment schedule.
Why does compatibility matter so much?
Because it decides both the cost and whether the conversion is possible. Model, control board generation and firmware determine whether a machine takes a straightforward retrofit, needs adapter hardware at a higher price, or cannot be converted at all.
What if some machines cannot be converted?
Then the payment decision has become an equipment decision. You are choosing between running two payment systems — which confuses customers — and bringing forward a retool you had not budgeted.
When is the cheapest time to do it?
During a retool. New machines arrive card-ready, installation labor is already being spent, and the compatibility constraint disappears. Converting mid-life on machines you will replace in three years means buying the same capability twice.
Are there ongoing costs?
Yes, and they belong in the decision. Processing fees, platform or software fees sometimes charged per machine, and gateway or kiosk fees. Those are recurring where the hardware is one-time.
Does it pay for itself?
Sometimes, through easier price changes, reload bonuses that lift average spend, and removing the exact-change constraint. It can also reduce revenue if part of your base has no card. Which effect dominates is a fact about your trade area, not about the technology.
