IoT Water Dispensers with Smartphone Payment

The project connected water dispensers—marketed by a manufacturer under six different brands—allowing end users to use their smartphones as a credit key to dispense products (still, sparkling, chilled water, etc.).

The service is subscription-based and targeted at businesses, public offices, commercial areas, residential buildings, and other facilities. It enables user registration and credit management in liters, from which each dispensing is deducted.
