You should remember the transaction charges. I think most payment systems charge 20-30 cents per transaction. I dont know about PP. I don't have a PP account and would probably object to giving you my CC number unless I found your service compelling. I certainly would not give it just to look around. This would probably turn off lots of potential users. Even an email validation is a turnoff, but not so bad as a CC number.
