Cardflight, the US firm which enables developers to integrate in-person card payments into their apps, has attracted $1.6 million in seed-round capital.

While much attention over the past week has been on Braintree which concentrates on online payments, Cardflight is offering the equivalent for transactions in shops or restaurants.

The firm said 90 per cent of credit card transactions still happen in person, giving it a bigger market to shoot at than Braintree, acquired by PayPal for $800 million, and Stripe.

Cardflight’s platform means developers can produce customised apps for retailers. The firm also supplies its own card reader to clients.

The funding round is led by FF Venture Capital, a New York-based VC firm that focuses on early-stage tech start-ups.

Cardflight’s customers are generally vertical solution providers or large and medium-sized merchants. The new funds will enable the firm to expand its workforce so it can pursue both markets more aggressively, it told Techcrunch.
