Our solution for swimming pools is developed purposely for the management of users in small, medium and large structures. Scalable software, specifically designed, manages information concerning users, sale of services and subscriptions, deadlines, book-keeping, courses and activity planning. Physical barriers are essential to separate the area dedicated to the public and that of paying users. The combination with a system of barcode and QR code issuing system allows the sale of single entrances to occasional users, while the MoneyCard system, for the payment of showers and hair dryers, allows to eliminate waste and to maintain a balance between costs and revenues.
