Actually, this could be an interesting and lucrative side business for banks, identity verification. You could have varying levels of verification, requiring varying levels of authenticating documentation and numbers of employees to review and vouch that could then be used to provide a certificate of verification for a service.

E.g. namecheap.com generates verification ticket item requiring valid identification and SSN that Bank of America then uses to verify your identity for $30, and vouched for the identity. Meanwhile Goldman Sachs generates a verification ticket requiring much more strenuous authentication, and the bank charges $200 for (with increased insurance, etc), which satisfies the much higher validation standard the Goldman Sachs requires to authenticate you for your ritrement account with over $X in it, etc.
