We bought our laundry machines from CSC. And we have a service contract with them for repairs. Our machines take your debit/credit card. Apple Pay Samsung Pay, google pay. And money goes directly into our checking account. CSC gets no other money from us other than that service contract monthly fee.
I was just camping in Milton, Florida. The campsite used the Laundry Boss. From the user end it was extremely user friendly, has an app for payment or an on-site card swipper.
