Cardspring is creating an application platform that will allow Web and mobile developers to write applications for credit cards and other types of payments. Cardspring attaches itself to the payment network in a secure fashion on one side, and on the other it presents itself as a platform for developers to create payment apps via Web-standard APIs. It is a bridge between the two networks. These applications could include things like electronic coupons, loyalty cards, virtual currencies, or yet-to-be-imagined commerce apps.

Essentially, its mobile payments and mobile commerce strategies — at least in terms of what investors and the public have been told — are nonexistent for the moment.
