One important item to note - WePay Clear is built for platforms - services that connect buyers and sellers like online marketplaces, crowdfunding sites & SMB commerce tools. We shield them from fraud losses by underwriting the merchants directly, and taking the losses ourselves when we're wrong.
It is not built for standalone e-commerce merchants to protect them from fraud. We are exploring this for the future, however - you can imagine that a seller using one of our platform partners need protecting too.
You can accept payments from anywhere, as long as it's a Visa, Mastercard, American Express or Discover. Sellers must be based in the U.S. or Canada, though expanding the scope of this is our #1 company priority.
