Fraud protection is an odd marketing angle. The merchant bank is the one that gets hosed due to fraud, so anti fraud technology helps Stripe, Paypal, WePay, etc. WePay is marketing that they are very good at not screwing themselves. There are clients that care about anti-fraud, such as ecommerce companies that ship high value electronics, but WePay has no experience in this category. The crowd funding space has fraud…
WePay specializes in two-sided applications-where you have buyers and sellers and you're moving money between them. There's a lot more to fraud than a bad credit card. See my other post RE: fraud.
