the all-knowing number
I have written a few times previously about the kennitala system in Iceland. The kennitala is a national ID number, but it's (almost) completely public. Anyone's full name, kennitala, and address are available on the web to anyone holding an Icelandic bank account. This was initially very spooky to me as an American, but as this new article points out, the openness of the system is perhaps its greatest strength.
