Additional Check-In Data┬Â

luca provides the functionality to associate a Check-In with additional data. This can be done by either the Guest App or by the Scanner Frontend. Additional data is designed to be non-sensitive data that can be used to narrow down possible contact persons among all guests of a venue. For instance, this might be the table number a Guest was placed at in a restaurant. Regardless of which app creates the Check-In, the additional data is encrypted using the venue keypair before being uploaded.
