Maestro One Click Pay, how exactly does this work?

You will always have 2 account numbers when making a payment transaction, one of which the amount will be deducted and one to which the amount will be added. The transaction between 2 accounts happens based on an agreement (= contract) between both parties. Such a contract can result in recurring transactions.  Through One Click Pay you can record data at once by making a standard payment by using a bank card and card reader. All recurring transactions with the same parameters can then be executed in 2 simple clicks: 'Pay' and 'Confirm payment' so that you do not need to endlessly repeat the same actions.
