We have created a completely free APP on the marketplaces that can be downloaded by visitors.Beacon devices are able to transmit their identification like a lighthouse that spreads light with well-defined rules and directions (the most recent generations also transmit short texts, for example a site URL, or detected temperature values)The signal transmitted by the Beacons can be received by any device with a Bluetooth connection by opening this app.Based on these technological assumptions it is possible to automatically pilot actions on all devices that are in the vicinity of a beacon and that have an active Bluetooth connection.
