Systems and methods for facilitating interaction between a ticket holder and a self-service function related to a ticket are described herein. A mobile device can detect proximity to a self-service function. The mobile device can activate an application related to the self-service function. The mobile device can communicate with a beacon to retrieve an identifier of the self-service function. A first connection session can be established between the mobile device and a cloud broker service while 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 using the first and second connection sessions by mapping an identifier of the mobile device with the identifier of the self-service function. Communications can be sent from the self-service function to the application of the mobile device through the cloud broker service including directional information.
