I want to have a product design that would facilitate the use of coin laundry machines. There are systems currently existing that allow credit card payment for entire laundromats, but not on an individual machine basis. Most machines are either $1.00, $1.25, or $1.50 per use. I want to come up with a small device that could be set up and charged on a per use basis that would directly pay the owner of the machine so the user would not have to always have quarters.
