They're European (Deutsche Telekom), which might be part of why they prefer to work that way.

In the city I used to live, they had to put signs up at the entrance to a street, warning people to ignore Google Maps. It tried to route people the wrong way up a one-way street, and the government had failed to get Google to fix it.
Even ignoring that though: including both the ID and detail allows it to work both ways. In official situations (e.g. at a country border) you might be able to validate against a server, but the local nightclub probably doesn't have access to a validation server.
One has no option but ADSL which reaches 8Mbps on a good day, the other is luckier and has Cable but only 100Mbps.
