A server-implemented method for automatically registering an asset tag in a database is disclosed. One or more asset tag collision reports are received from at least one mobile device connected to the server, each report including a tag identifier of the asset tag that is wirelessly broadcast by the asset tag. A location of the asset tag is determined based on the one or more received asset tag collision reports. A first asset is selected from a set of unregistered assets that are identified as being deployed in the indoor facility based on determining that there is a match between the location of the asset tag and location information associated with the first asset. The asset tag is then registered in association with the first asset in the database.
