>If you don't mind me asking(...)how is this score calculated, how does it aggregate all your financial information without a specific identifier We do have an specific identifier. Each person has an ID card, with an ID number. The ID number is not secret at all and used for many things everywhere. By the way, we don't have anything like a "social security card". Even kids have this ID card, their parents can (and ought to) request one for each kid. This ID number has nothing in common with your birthday or anything. It is mostly a sequential number. All aggregations are done using this (unique) ID number. So financial companies submit payment data associated to your ID number. So later credit scores can be computed as well. The difference with this ID number versus the SSN is that our ID number is not used as a password of any sort. How do companies or government institutions check out if you are who you say you are? They can take a look at your ID card. And usually they do have fingerprint scanners and signature scanners to check against the government's central ID registry. By the way, last year we issued the Electronic Id Card, this one has a security certificate (public-private key cryptography) associated with it, and each person chooses (and keeps secret) a password. This password never needs to be revealed to anyone. With this password one can do digital signatures of any document, etc.

Nowadays SSNs are generally issued at birth, particularly since the IRS wants one for each dependent listed on the tax return. I believe this has been the case for at least twenty or thirty years; certainly my card dates from when I was born. > This ID number has nothing in common with your birthday or anything. It is mostly a sequential number. If it's a sequential number requested near birth that would mean that most people with the same birthday have similar numbers, doesn't it?

  > If it's a sequential number requested near birth that would mean that most people with the same birthday have similar numbers, doesn't it? In practice it is not requested near birth. It is sequential to the time you asked for an ID card, so people who asked for one in the same timeframe get a close number
