Patent application US20130117185 from Stripe is for a “Method for conducting a transaction between a merchant site and a customer’s electronic device without exposing payment information to a server-side application of the merchant site”.
It seems to me that a similar method (client-side credit card tokenization) is already adopted and implemented by many payment providers (Braintree, CardVault, VantageB2B, PayLeap, and many others), unless I missed some subtleties of the aforementioned patent which would allow distinguishing Stripe from the competition.
Could someone help to clarify which part of the Stripe patent application is really unique compared to what the competition does?
