I feel this is a really silly question that has an obvious answer I just can't fathom.
Ok so on social media I'm often seeing posts where someone found a dog in the street. Someone always asks if anyone has a scanner then another member of the public pops up saying they've got a scanner and they are on the way to scan the dog.
But what use is their scanner anyway? It isn't going to tell them who's dog it is as they can't access that information anyway and they still need to take the dog to a vet then get the vet (who does have access to the database) to scan the dog so that the vet can contact the owner.
What am I missing here? Reason I ask is I was actually going to buy a scanner then thought hang on...all it tells you is the chip number so what's the point?
