Foursquare is launching a cool new partnership with American Express this week at South by Southwest in Austin, as the WSJ first reported.
It's a pilot test of a new system that lets your credit card company reward you with a special deal — after it has verified that you have checked in someplace on Foursquare.
This gives you many incentives: To shop with participating merchants, to check in on Foursquare, and to use your AmEx card.
