Flint has raised $6 million to expand its staff and boost development of its mobile payments application.
The investment round was led by Diegicel and SVG Ventures. Previous investors Storm Venturs and True Ventures also contributed capital as a followup to their April 2012 investment.
Flint charges 1.95% per transaction for debit cards and 2.95% for credit cards. Its technology uses the phone's built-in camera to scan card numbers. Flint also provides data on customer activity and access to Facebook marketing. Flint is targeting merchants such as photographers, consultants and fitness trainers.
"While many others in the industry are replacing retail POS systems and cash registers with tablet apps, we're focused on empowering the 'non-countertop' businesses that operate outside of a store and have different requirements," says Greg Goldfarb, Flint's co-founder and CEO, in an Oct. 25 press release.
