Payment using a payment card for goods and/or services ordered online via an information network such as the Internet is implemented in a notably secure manner without the need to transmit the client's payment card number over the data transmission network. A separate confirmation for effecting the payment for an order is requested from the client. The information to be confirmed is transmitted to the terminal device of the client, such as a mobile station, by means of which the client confirms the order by digitally signing the confirmation request. The digitally signed confirmation and the electronic identity information associated with the client are then returned to the payment service equipment, which verifies the client's identity, checks the validity of the client's payment card, and then transmits the necessary payment information to the payment system.
