Social app developer Fan Appz has just announced that it has integrated its platform with Facebook Places. The company says this gives businesses "a powerful and easy way to create highly relevant offers based on a customer’s offline activities."

That doesn’t sound bad. 

This would be he first social marketing platform to integrate with Facebook Places, according to Fan Appz. It will allow consumer brands, retailers and local businesses to reach, engage and reward any customer that checks-in via Facebook. 

This is exactly the kind of thing that makes Facebook such a potent weapon in the check-in space. You’ve got the enormous user base, the brand recognition, and the developer community creating new opportunities for businesses, giving Facebook Places a distinct advantage over competitors like Foursquare, Gowalla, and the rest.  

"Fan Appz has seen tremendous growth over the past year, as tens of thousands of businesses have used our platform to engage and build stronger relationships with customers," said CEO Jon Siegal. "With Fan Appz Offers for Facebook Places, companies can now take their Facebook marketing to the next level by rewarding fans for their interactions in the physical world."

FanAppz also makes a note that its suite of solutions is "highly measurable", which is obviously an asset when you’re talking about social media marketing.
