That is why epassport was origionaly created. If the person was denied by Epoch/Paycom (and hopefully soon other ISPS), they were given the option to signup for epassport with their Credit Card, which has a lot lower scrubbing. So, once they sign up for their epassport card, then they can subscribe to the paysite easily. I believe all major ISPS (ccbill, epoch, etc) support epassport cards. So, basically, yes, does work for most adult site subscriptions, not all places online though that aren't adult.
