At least 3 credit card companies I use are signed up/using a biometrics/information provider. (they wouldn’t tell me who, despite federal disclosure requirements — I only knew they were using someone because my current accurate info was replaced by info from 7 years ago)
There are companies trying very hard to find out everything from your hair color, facial features, and skin type to your email address and connect them all for everything from identity management to advertising. They are working on getting your payroll data directly from your employer as well, so you will not be able to self declare income in the future. You will know when you run across the companies that use these providers because their data is often wrong or out of date and they usually ask you for a video of yourself holding your id to update it and may even give you a problem then.
The amount of information these companies are collecting and piecing together is scary — one company is tracking major website comment activity and tying it back to their core data sets which has your IRL info.
This means that in the future, you could be denied employment, a mortgage, or an auto loan because of something you said last year in Twitter.
