The app makes it possible to pay for washing machines and dryers on all machines with SaniPay sign. The app scans for SaniPay machines, the machine is selected, amount is determined, and payment is executed in the app from the attached credit card in MobilePay, Paypal or other available payment system. Once the payment has been completed, the machine will be notified of the transfer via an encrypted Bluetooth connection. Do not close the app before the machine has registered the payment.
