The invention relates to a method for securing trade. A customer establishes a data communication contact with a server, which is at least in a data transmitting connection with a service supplier. After the data transmitting connection has been established, selects, confirms and/or makes a payment for his/her acquisition, such as buying a product, a service and/or a gambling contract. The server, if necessary after verification of e.g. personal, communication and/or credit information, confirms that the purchase transaction has been conducted correctly and drafts an electronic substitute. Transmitting or selling of the electronic substitute is carried out through the server.
