CardFlight connects mobile developers with payment processors. CardFlight brings the same developer‐friendly, transparent approach to payment processing as Stripe and Braintree. However, CardFlight focuses on the ~90% of payment transactions that happen offline. Developers retain full control of their integrated app experience, and use Cardflight’s encrypted mag stripe reader and SDK/API so that they can safely and securely accept card present payments in their apps, with support for their existing merchant account.
