An iBeacon continuously broadcasts three identifiers: a UUID, major, and minor. UUID is a long random identifier that should be customized for each implementation. Major and minor are integers between 0 and 65535 that can be used to differentiate each individual beacon. For example, a retailer may have one UUID across all of their iBeacon deployments used for their retail customers, and another UUID used for employees. Each store may have a major identifier, and each individual beacon would have a different minor identifier.
