The document discusses Kalerion, a company that created a mobile dating application using Bluetooth proximity to detect matches. The application works on both active devices that can run the Bluetooth application natively, as well as passive devices that cannot run the application but support Bluetooth. Kalerion also introduced an affiliate program where other companies could co-brand and link to Kalerion's content and party map to find matches. Subscribers' devices have a unique identifier that allows them to detect and identify other users within Bluetooth range.
