Empyr Charges Retailers for In-Store Purchases Linked to Online Ads
Empyr uses geo-fenced advertising to make offers to people near a store. But its real differentiator is connecting ads to in-store purchases. It does this by offering consumers rewards for registering their credit cards, serving those consumers ads on partner Web sites, and charging retailers a fee when the consumers make a purchase. Part of the trick is deep integration with the credit card companies to gather the purchase data.
