We can use iBeacon as name tag , so when group leader need to call people gather together he can use iPad or iPhone to tell who is nearby.
When travel in group, the guide will have to count people and bags every time. If we put a iBeacon for every people and bags, then in no time we can know what is missing.
by the way,
iBeacon as Dog tag is not bad. Maybe Cat tag. Since cat like to wondering around.
