SUBSTANCE: invention relates to a security server, a payment recipient device, machine-readable media, a method of establishing a link between a payment recipient device and a client payment application and a method of receiving payment recipient device authorisation from the security server. A method of receiving payment recipient device authorisation from a security server comprises receiving a client identifier; sending a first message to the security server, wherein the first message contains a client identifier, an application identifier which indicates a client payment application, and a security token for the payment recipient device; receiving a second message from the security server, wherein the second message is received only when it is determined that the payment recipient device is authorised by the scheme provider, wherein the client payment application is contained in a security element, which is configured to be contained in a mobile communication terminal; and establishing a secure channel with the security element of a mobile communication terminal to make a payment using the client payment application.
