What is UUID, major and minor number on Beacons?

BLE Beacons (iBeacons) are identified by three properties. They are: Major number, Minor number and UUID. The combination of these three numbers is unique for each device. The numbers are normally preset on the beacon and you simply enter them in the CMS when you register the beacons with our system. Alternatively, you can see these numbers in an app provided by your beacon supplier.
