Flint Mobile has rolled out new social marketing and customer management features to its mobile payment app.

Flint, of Redwood, Calif., lets merchants accept payments by snapping a picture of a card and using imaging technology to translate the photo into transaction data.

One of the new tools in the updated mobile app lets merchants filter transaction data by entering parameters such as purchase date or transaction amount, for example, as well as download the data along with customer email addresses. The startup also said it simplified how merchants can integrate their payment process into their Facebook marketing efforts. In doing so, consumers are prompted to post ratings and reviews to the social network from the electronic receipt of every transaction.

Flint, which announced the features in late January, said its iOS app has been downloaded by more than 20,000 people, and the average transaction processed through Flint is upward of $100.
