An identifier comprising readable ID information related to the identifier is associated to a product or product type so that when selecting said product the corresponding identifier ID is read and transferred to a server as a query by a user related communication device, which may be e.g. a mobile station or cash machine. The server is configured to be in a data communication connection with a database comprising identifier ID and content information of each product or product type. The transferred identifier ID is then connected with content information of the product or product type with corresponding identifier ID at the database, after which said content information is transferred as a response to said query to said user related communication device.
