How Do Card-Operated Laundry Systems Change the Buildout?

By Jeremy Mills, CEO & Founder, Apex Grid Engineering — USAF Veteran. · Updated 2026-09-15

Card-operated laundry systems change the buildout by adding network infrastructure where coin handling used to be: card readers on machines, a site gateway, and reliable wired or wireless connectivity, plus reader power and a small network enclosure. The utility design — water, gas, power, drainage, ventilation — stays the same as any laundromat.

The concise answer

Card-operated laundry systems change the buildout by adding network infrastructure where coin handling used to be: card readers on machines, a site gateway, and reliable wired or wireless connectivity, plus reader power and a small network enclosure. The utility design — water, gas, power, drainage, ventilation — stays the same as any laundromat. The mental shift is treating connectivity as a utility. Owners will spend weeks selecting washers and then accept whatever internet the landlord provides. I flip that: the payment network gets specified, drawn, and tested like any other building system, because on opening day it's the difference between revenue and a room full of machines nobody can start.

The network as a building system

The design starts with the payment platform's requirements — reader power, gateway placement, and whether the system tolerates offline operation. From there I lay out data drops or access-point positions to cover every machine bank, keeping in mind that washer and dryer cabinets are steel boxes that eat radio signal. A gateway or network enclosure needs a home: cool, ventilated, lockable, and on battery backup so a power blip doesn't take down payment. Redundancy is a business decision I make sure the owner makes explicitly. A store doing high volume justifies dual internet connections; a small store might accept the risk. Either way, the failure mode is documented before opening, not discovered during the first outage. I also coordinate camera and reader networks so a single switch failure doesn't blind both payment and security at once.

Card-laundry infrastructure checklist

The buildout items below are the difference between a card store that just works and one that generates support tickets. I confirm each one before final inspection. Small items, outsized consequences — check them all.

  • Data drops or surveyed wireless coverage reaching every machine bank through the steel
  • Gateway and switch gear on UPS battery backup with documented runtime
  • Network enclosure ventilated and lockable, out of customer reach but accessible to staff
  • Reader power coordinated with the machine electrical rough-in, not added as an afterthought
  • Documented offline behavior: what happens to payment during an internet or power outage

What else do project teams ask?

Does a card laundry still need change machines?
Usually not for machine payment, though some owners keep one for vending. Eliminating change machines frees floor space, removes a cash target, and simplifies the electrical plan. The design trade is that you now depend on connectivity — if the network dies, nobody can start a machine.
Wired or wireless for the card readers?
I prefer wired drops to each machine bank wherever the buildout allows it — conduit is cheap during construction and wireless inside a room full of steel washer cabinets is genuinely hard. Where wireless is the only option, I design for commercial-grade access points with a proper site survey, not a consumer router on a shelf.
What happens when the internet goes down?
That depends on the payment platform — some systems queue transactions locally and sync later, others stop. I ask the owner which platform they're buying and design the network for redundancy accordingly: dual-WAN where the business case supports it, battery backup on the gateway and network gear, and clear documentation of the failure mode.
Do card systems change the electrical load much?
Barely. Readers draw little power; the meaningful additions are the gateway, network switches, access points, and any kiosk or value-add station. The electrical design change is small — the design-discipline change is large, because now the network is life-safety-adjacent for revenue.
