The same seven signups. One more paying customer.
Every signup gets a card check at the door. Real customers pass, throwaway cards bounce.
Without a card check, all seven signups enter the trial. Three arrive on cards that will not hold up, so only two of the seven ever pay, which is 29 percent. With 1Capture those three are stopped at signup. One of them comes back with a real card and becomes a customer, so five enter and three pay, which is 60 percent. That is one more paying customer from the same seven signups.
