Many self-service laundries have a change machine that dispenses tokens to use in the laundry machines. This allows to accept payment methods without staff and a limited investment as the tokens can be used in any machine in the laundry salon.
Self-service laundries are an indoor application, but the customers often have wet hands due to the wet laundry. A corrosion free material is therefore recommended.
The customers are often recurring, so a custom made token is recommended rather than a generic standard token. This increases customer loyalty and reduces risk of receiving tokens from other companies.
