The LaundryPass Contactless Card Reader can be easily attached to any washer or dryer. Availablity times and price can be set per hour, day, or week, with increments by the cent. For additional fine-tuning, we offer the MP models, which are outfitted with a multi-price button, that enables additional price options for use with stackable machines, or for selectable run times or top-offs. Comes with plug and play connectors, that can be easily installed by replacing the coin acceptor.
