Caller ID is EXACTLY how it works according to the website.

That's interesting... no call costs?
I wonder if it just doesn't answer the call, and uses caller ID to
'authenticate' the user.
If so, isn't that a bit dodgy, as a phone that's 'borrowed' for 10 secs
from
a coat in a pub, could be used to open a locked office 50 miles away...
Either that or a quick phone call from a landline with spoofed caller ID
data...
Hmmm....
