8. Payment methods

Two payment methods to convert money to water credits on a

and collect the money from the water consumers. The sales

8.2 Mobile payment

product.
The AQtap includes a mobile payment feature in collaboration
with local mobile operators. The payment process between the
requester of water credits (smart card holder), the mobile wallet
provider and WMS is routed via a secure connection.
The smart card holder needs a mobile wallet account and uses
his mobile bank interface to purchase water credits. As the mobile
bank interfaces differ significantly, we will inform locally about the
operational details.
When the mobile bank transaction is completed, the water credits
are available for download directly at the AQtap.
8.2.1 Water credits purchase via mobile payment:
Note
The smart card holder requests water credits from the mobile
bank, giving information on:
• amount of water credits
• smart card number.
If the request succeeds, the mobile bank sends a notification of
approved payment. Water credits are available at the AQtap.
If the request fails, the mobile bank sends a notification of
rejected payment.
Reasons for a failed request can be:
• invalid request
• no money in the mobile wallet
• transaction limit reached, see section
smart cards
• unknown smart card (check if AQtap has been connected to
WMS after first transaction)
• invalid smart card (blocked in WMS)
• wrong smart card number.
