Detect device in the range

Is it possible to develop an computer application (best in Java for my case) which will be notify each time a mobile device enter in the beacon range?
In fact I would like to monitor customer devices and generate something like a dashboard displaying mobile name or UUID, date and distance of the beacon.

Thanks.

Hi Bertrand,

Thanks for your question!

It would be possible to gather such data showing number of times a device appeared in beacon's range.

The first step would be to build a mobile app, which has to be installed by the users. The app combined with a backend could aggregate such data.
