The Data Behind Purchasing Behavior at UserVoice – Pricing for Conversion

At the same time, the extra people signing up were not good leads. These new users rarely completed the steps to start using their account, those that did submitted more support requests, and the conversion rate to paying customers at the end of the trial was more than halved.
I ended up putting the credit card requirement back in.
We have seen as well that there is less dedication from a customer when they sign up without a credit card. People sign up and forget about it, because it isn't paid anyway (even when you send them regular update emails). When requiring a cc for sign up the user is more motivated to actually trial the product and see if there is a fit.
It basically shifts the drop by sign ups from the actual users who want to use your product for a longer period.
Above is all from B2B experience. B2C can be totally different.
