Your Personal Information
Ever wonder how companies all seem to know the "last four of your social" or Date of birth. Credit card numbers? It's because we give it to them. Should you? I don't believe so but it has become commonplace and a big problem.
Hundreds of millions of records are stolen every year. All of the above can lead to serious consequences for you.
Social Security numbers were never inteded to be used as a personal identifier for everything. The trend is slowing HIPPA rules and Helath Insurance carriers are giving us I.D's rather than SSN- (but still asking for SSN I Don't know why)
Protect yourself. Don't be so quick to spew out your birthdate or Social number. Only in rare instances does some 3rd party really need it.
