How's that any different than "In order to qualify for this loan, you must consent to a body cavity search which will be conducted by the guy we hired in the next room"? I suppose you can make the argument that Experian is doing a bad here by being a part of a system that helps employers get private information about you, but that seems somewhat different than the OP which implied something like "experian is gossiping about you behind your back!". It's the difference between providing cavity search as a service (with consent) compared to selling your nudes on the darkweb.
The point is that the bank has no way to perform this body cavity search itself. If Experian didn't exist, it would have to use other means of assessing risk, like all the banks in countries that don't have an Experian do.
The point is that perhaps it shouldn’t be necessary to submit to a cavity search just to get a loan like that. Maybe it should even be made illegal to require something like that.
>With a consumer’s consent, lenders can request the information from Experian and an income and employment report can be delivered to lenders [...]
