I would like the community thoughts on this as we are in the secondary gift card space.We are "ATTEMPTING" to build a payment processing system similar to stripe but for gift cards where payment processors can augment their payment processing capabilities through the use of gift cards or merchants directly can integrate our service to accept gift cards as a form of payment. IE an end user can pay for an item or service say with a walmart or best buy gift cards. We already have the ability to do instant balance verification for gift cards. What do you guys think about this?

When dealing with thousands of gift cards how do sites like raise.com or ejgiftcards.com validate gift card balances? Is there an api do such a thing?
