We created a system that take cares of the billing of laundry room usage. Many property owners would like to bill for the usage of the laundry room but naturally they do not want a coin/token system. We created a system that connects a booking system with the actual door tag access control. The combination of thees two systems we can monitor the actual usage of the laundry rooms. The system collects all the data and once per month sending the correct usage to the property billing system. Doing usage billing saves both the environment and frees up the bookings of the laundry room. This is since you do not want to pay for something that you do not use and when you use it you tend to fill up the machines more efficient.
