Flint’s iOS and Android swipe-free mobile payments app takes credit cards on the spot by scanning instead of swiping, via invoice-based bill payment or online. All transactions are conducted via the mobile device’s camera without the need of any external hardware. The Flint platform also offers a range of business productivity features including data-syncing with QuickBooks Online, digital coupons, team account workflow, and a merchant portal for advanced account management and analytics across all channels. As a secure Payment Service Provider, it also provides instant setup without a merchant account and low transaction fees. Flint Mobile.
