Enter banking details on sign-up - good or bad idea?

[KasinoKing]

At most casinos players only have register their basic details (Name, e-mail, etc) when they first join.
I believe people do this to suss out a casino in fun-mode first.
Then later on, if they decide they want to deposit & play, they have to input their full address and details of a means of depositing money into the casino.

However, I casino I encountered recently will only allow players to register if they input valid Credit Card details on the initial sign-up.
If you don't give this detail, you can not complete your registration.

Do you think this effects whether players go through with the registration, or are turned off so much they just don't bother with it?

Thanks in advance for your votes!

I have read a research (I can find it somewhere if you are curious, I think I still have it somewhere), that every plus field you put into a form, that are not really really really required will reduce the subscriptions by around 5-7% per plus field.

I would stop registering if I need to give out my credit card data on signup. And what if I would like to use another deposit method?

I usually sign up as a player to the properties I promote, and what I saw is that there is a direct correlation between conversions and the ease-of-use/simplicity of the signup forms.
