CC/App payment per us washer dryer for 1-2 family rentals

[Matthew Banks]

We have several 1-2 family rentals in a neighborhood that gets a mix of students, grads, and professionals. The competitors all provide washers/dryers, some free and some coin-operated. We have washer/dryers as well, but are constantly having to do repairs. The tenants are likely over-stuffing them. I'd like to charge a per use fee to at least help recover the cost of repairs each year or buy new machines. I'd strongly prefer to have a cash-less payment mechanism though, ideally a phone or a card that you can add funds to with a credit card or phone, so that tenants aren't forced to use coins or cash bills. (It's a modern inconvenience to force tenants to get coins or bills from a bank, and then we're also stuck handling coins as well.) Anyone have recommendations for options? We have 2 pairs of washers/dryers that are currently coin operated that we could convert. And we have non-commercial machines in the other properties that I'd like to convert to a pay per-use.
