Abstract: Systems and methods are described for facilitating interaction between a ticket holder and a self-service function related to a ticket. Using a mobile device, a machine-readable code is scanned associated with the self-service function to retrieve an identifier of the self-service function and to activate an application or a web session on the mobile device. A first connection session can be established between the mobile device and a cloud broker service. A second connection session can be established between the self-service function and the cloud broker service. The cloud broker service can generate an end to end session via the first connection session and the second connection session by mapping an identifier of the mobile device with the identifier of the self-service function. The self-service function can communicate through the cloud broker service to the application of the mobile device.
