CardFlight which lets developers integrate in-person card payments into their own app raised $1.6 million in seed-round funding, led by ff Venture Capital, a New York-based venture capital firm that focuses on early-stage technology startups. While a number of payments startups are focused on online and e-commerce payments, CardFlight focuses on the 90% of credit card transactions that are ‘card present’ and happen in person. Additionally, CardFlight clients are typically vertical solution providers or large and medium-sized merchants, in contrast to companies that only provide closed mobile payment offerings that do not allow customization or white-labeling.
