The invention describes a method for securing payment of amounts of different levels by means of an arbitrary payment method for arbitrary goods, and in particular for delivering services that are to be paid for to a customer via packet-oriented open networks, in particular the internet, including the usual security standards and encryption methods, with the usual access software, regardless of the operating system, in which after a customer request, a ticket pair (6; 10) is generated by a merchant (3), and a first ticket (6) is transmitted indirectly via a customer (1) to a payment provider (4) and a form (7) for payment confirmation is transmitted by the payment provider (4) to the customer (1). After the required information about the customer and about the desired service (6) has been entered and the filled-out form has been transmitted along with the first ticket (6), these are on hand as payment authorization at a payment provider (4) so that the applicable amount can be booked to the merchant's account. That the bookkeeping operation is done once the customer data have been validated by the payment provider (4) and the second ticket (10), transmitted from the merchant (3) to the payment provider (4), is on hand as a response to the request of the payment provider (4) for validation of the first ticket (6) by the merchant (3), which, modified with customer data by the payment provider (4), was transmitted to the merchant. That the customer (1), after payment, receives access to the service (5) via the network (2), once the second ticket (10), transmitted by the payment provider (4) to the customer (1), has been correlated and validated by the merchant (3) by interaction with the merchant and the release has been granted.
